case. Designing a pile group is a difficult and sometimes very time-consuming task. One of the main reasons is that a pile group has a great number of input parameters and variables. There are geometric parameters such as the pile cap thickness, pile type and diameter, location, angle of rotation and batter (slope) of the piles and pile length.
To observe the design capacity, a test pile is constructed and estimated load is given upon the designed pile. There are three kinds of static pile load testing. 1. Compression pile load test. 2. Tension pile load test. 3. Lateral pile load test. A lobal Journal of Researches in Engineering V olume XVI Issue IV Ve rsion I 41 Year 201 E
PHC pile, with a diameter of 1000mm and a wall thickness of 130mm , is adopted for the wall pile frame structure of this project. The pipe pile prefabrication is carried out by dalian prefabrication factory. The parameters of the PHC prestressed concrete pipe pile are as follows: Table 1 parameters of PHC pile of wall pile frame structure .
sheet pile and ground vibrations during sheet pile vibratory driving. And second, to analyze a selected portion of the collected data with focus on the sheet pile - soil vibration transfer. Both aspects of the thesis work aim, more generally, to contribute to the understanding of ground vibration generation under vibratory sheet pile driving.
2.2 High-Strain Dynamic Pile Testing. 2.2.1 The contractor shall perform dynamic pile testing at the locations and frequency required in accordance with section 4.0 of this special provision. 2.2.2 Dynamic pile testing involves monitoring the response of a pile subjected to heavy impact applied by the pile hammer at the pile head.
The pile driving analyzer (PDA) was developed in the 1970's as a method to directly measure dynamic pile response during driving. As the name implies, it was developed to analyze pile driving and evaluate pile driveability, including the range of stresses imparted to the pile, hammer efficiency, etc.
to pile cap resistance to lateral loads. The focus of the literature review was directed towards experimental and analytical studies pertaining to the lateral resistance of pile caps, and the interaction of the pile cap with the pile group. There is a scarcity of published information available in the subject area of pile cap lateral resistance.
The nonlinear springs are defined using API p–y curves at regular depth . intervals, where p represents the lateral soil resistance per unit length of the pile and y is the lateral deflection of the pile (API, 2007). As it was discussed before response of a single pile is different from response of a pile in a pile group due to group effect. One of the most common methods of accounting for .
4. The next step is the design of pile-groups, which settlements are larger than that obtained for a single pile. However this research evalu-ates a single pile, which can be considered as a first step in design of pile foundation. Settle-ment of a single pile is a prerequisite for esti-mation of pile-group settlements (either from
pile bending stiffness, the modulus of subgrade reaction (i.e. the py curve) assessed based on the SW model is a function of the pile bending - stiffness. In addition, the ultimate value of soil-pile reaction on the py curve is governed by either the flow around failure of soil or the plastic hinge - formation in the pile. The SW model analysis for a pile group has been modified in this study .

In order for a pile to penetrate under one blow of the hammer the impulsive force transmitted by the ram-cushion system must be of sufficient magnitude to overcome the inertia of the pile as well as yield the soil along the side o.f the pile and at the point. Once
capacity are not enough to cover the combination of the tension and lateral load applied on the pile head. In this case we need to somehow increase the pile capacity (increase pipe section or use an external casing on the top of the pile). Table: Analysis and Checking Summary table. Figure: Pile bearing capacity (cylinder method) and settlement.

Each sheet pile consisted of two 32-inch wide, 40-foot-long Z-shaped steel sheet piles interlocked to form a "paired" or "double sheet" pile that weighed approximately 4,000 pounds. The sheet pile was not secured to the crane; it was only held by the hydraulic clamp on the pile driver. When the sheet pile was being driven

within some of the piles to measure lateral pile deflections. Measured results were presented for a pile that had a diameter of 1.2 m and was located 5.7 m away from the tunnel axis line. At the pile location, the depth h of the tunnel axis level was approximately 15 m. The pile was treated as a single pile and the analysis was done.
vibratory hammer to install the entire sheet pile proposed cut-off wall was not feasible. The Port's engineer has developed an alternative system; a combination pipe pile and sheet pile wall ("combi-wall"), which consists of -six (ninety96) 20-inch steel pile with sheet pile supported between each pair of pile.
The most common pier construction consists of open, pile supported structures which include a decking system constructed on a pile foundation. The foundation contains a series of evenly spaced pile groups, or bents, as shown in Figure 2. The pile bents may be further strengthened to resist lateral loads by the addition of batter piles or by .
The six-pile group for the model in Figure 1 consisted of 1.17-m diameter piles with a large pile cap embedded in the nonliquefied crust. The pile cap provided fixed-head restraint at the connection with the piles. Some tests contained a single-degree-of-freedom superstructure fixed to the top of the pile cap, and
Pile designers therefore looked at calculation based on theoretical soil mechanics. 16 Geotechnical Design to EC7 13 January 2017 Layer 1 Layer 2 Layer 3 L 1 L 2 L 3 Q s1 Q s2 Q s3 Q b Ultimate pile resistance Q u Q s Q b Traditional Pile Design to BS 8004. 17 Geotechnical Design to EC7 13 January 2017 Traditional Pile Design to BS 8004 The usual approach is to divide the ground into .

on each pile head, where each zone may be up to three times the pile diameter in width. In BS 5400 the corresponding zones are limited to only one pile diameter in width over each pile head. The Eurocode for concrete design (BSI 2004) has less specific guidance for pile caps (Clause 9.8.1) than the UK Standards.
Design of pile group Most of the pile foundations consist not of a single pile, but of a group of piles, Which act in the double role of reinforcing the soil, and also of carrying the applied Load down to deeper, stronger soil strata failure of the group may occur either by the failure of individual pile or as failure of the overall block of soil the supporting Capacity of group of vertically .
