摘　　要：通过对四、六桩厚承台的有限元计算,分析其传力机理和破坏机理,进而得出四、六桩厚承台的拉、压杆传力模式,指出四、六桩承台的破坏主要是压杆的劈裂破坏以及在相同配筋率的形式下,不同的配筋形式对承台承载力的影响。Through the finlte-element calculation of the thick four-pile and six-pile caps, it analyses its force transferring mechanism and destroying mechanism, according to which it gets the force transferring pattern of pulling rod and pressing rod of the thick four-pile and six-pile caps. The main destroying form of four-pile and six-pile caps is the cracking of pressing rod. It analyses the influence of different reinforcement forms to the loading capacity of cap under the same reinforcing rate.
