以几种可能的桩基础平面布置方式为研究对象,通过3D有限元计算,就群桩基础的沉降与桩顶荷载这两个主要问题对前述桩基的不同布置形式进行了分析评估。以尽可能地发挥桩的承载能力、减少沉降和降低工程数量为主要目的,探讨了上述几种桩布置形式的优缺点,并提出了相应的桩型布置的原则与建议。
Taking several possible pile foundation layouts as the research objects, the different layout forms of the pile foundation were analyzed and evaluated based on the two main problems of pile foundation settlement and pile top load through 3D finite element method. With the main purpose of exerting the carrying capacity of the pile as much as possible, reducing the settlement and reducing the number of projects, the advantages and disadvantages of the above several types of pile arrangement are discussed, and the corresponding principles and suggestions of the pile arrangement are proposed.
