Battered pile and pile group are generally used in bridge , wharf and foundation of transmission power 斜桩以及有斜桩群桩广泛应用于桥梁、码头以及大型输电线路基础等。
There is less research about bartered pile and pile group . in this paper the " generalized elastic theory " is proposed to solve the problem 目前对于斜桩单桩和有斜桩群桩承载特性的研究,还鲜有文献报道。
( 5 ) according to the relative theory of method of code , and connecting the project , compiling computer program , settlements of the pile groups for cast - in - situ piles with expanded branches or plates are carried out and analyzed ( 5 )利用《规范》法中的有关理论,结合工程实例,编制了计算机程序,对挤扩支盘桩群桩的沉降进行计算和分析。
Under the vertical load , the vertical pile group has bigger bearing capacity than the battered pile group . under lateral load , the positive battered pile group has bigger bearing capacity than the vertical and negative battered pile group . both model experiments and prototype experiments are conducted 与单桩类似,竖向受荷直桩群桩承载力比斜桩群桩大;水平受荷群桩, “正斜”单桩组成的群桩比直桩群桩和“负斜”单桩组成的群桩的承载力大。
At last , the resultes are compared with those without adoption of random field model and the reliability of pile foundation under vertical load is systematically studied . the conclusion is that the interaction of piles group - soil - pile cap has great effect on the reliability of the pile foundation 并与未采用随机场模型的计算结果相比较,对竖向荷载下桩基可靠性进行了较系统的研究,说明桩群?土?承台相互作用的特性对整个桩基础的可靠度有很大影响。
