Pile cap is designed for the column loads plus the self-weight of the pile cap and the soil above the cap. Sometimes, due to its unique geometry, the difficulty may arise in the design of a pile cap, and it should be designed for moment and shear as deep beams, if applicable [4]....
As it is not always obvious whether a pile cap is slender or deep, and some pile caps may be somewhere in between, a general shear design procedure for pile caps can be accomplished by the following. First, choose the initial pile cap depth using the traditional ACI Code one-way and ...
桩基种类（Piletype）桩基种类（Pile type）Pile foundation, classification 1, according to the position of the cap The force and deformation of high cap pile foundation, which is higher than the ground floor, is different from that of low pile foundation. It is commonly used in bridge and wharf...
The relative levels of the top of the test pile cap and the underside of the main reaction beam should be arranged so as to minimise the depth of any additional packing above or below the load train which might otherwise lead to some instability in this area of the test set up. ...
made by the welded steel pipes and were bolted together in the field.The construction of the pile cap for the pier by the cofferdam has already been a complete success and the cofferdam used for the construction is presented herewith in aspects of its structural comparison,design and ...
and then a clutch is released to drop the hammer. The ram falls by its own weight, striking a pile cap and the pile itself. The hoist from the crane then lifts the ram back to the desired stroke. Standard weights for drop hammers are 500 to 10,000 pounds, with drop heights of appro...

the toe resistance and the soil reaction beneath the pile cap and uses separate group efficiency factors for each of the resistance components. This paper introduces relevant general design requirements, load combinations, characteristic values of the pile capacity, partial factors for loads and resistan...
Get PDF (386K) Keywords: lateral load distributions; grouped piles; pile-to-pile interactions Abstract The load distributions of the grouped piles under lateral loads acting from one side of the pile cap could be approximately modeled using the elasticity equations with the assumptions that the und...
This design is for the construction of foam piles 20 in unstable base soils comprising silts and/or sands and/or gravels that are compacted. The compacted base soils 21 are agitated to loosen and break up same by mechanical, hydraulic, pneumatic, seismic or other means. An injection probe ...
