摘要
针对基坑工程预应力锚杆柔性支护的工程特点,依据蠕变力学理论和有限单元数值法的特点,对锚杆、浆体的受力、剪应变率、安全系数和位移进行了数值计算和分析,从而推广该支护方法在基坑中的应用。
Based upon the project features of prestressed anchor flexible support in foundation pit project, it calculates the force of anchor bolt and mud, shear strain rate, safe coefficient and moving and makes an analysis according to creep mechanics theory and the features of finite element numerical method, sa as to promote the application of this support method in foundation pit.
