摘要
结合桩锚支护的工程实例,选用合适的土体模型和接触面,运用预应力锚索施工过程的简化模拟方法,对预应力锚索和围护桩与土体的相互作用进行了模拟,得到该基坑施工过程的地表位移,沉降,围护桩位移,受力和锚索轴力,并根据计算结果分析了该基坑支护方案的可行性。
Combined the engineering example with pile and anchor supporting,selects the suitable soil model and contact area element,use a simplified method to simulate the operation process for pre-stressed anchor.The interaction between pre-stressed anchor and enclosing piles with the soil body was simulated.The ground surface displacement,displacement and loading of enclosing piles,axial of pre-stressed anchor have been obtained.Base on the results obtained,the feasibility of supporting scheme was analyzed.
