摘要
在考虑基坑顶面荷载作用位置的情况下,从锚杆排列方式入手,结合工程实例,利用理正软件求得桩身最大位移,编制MATLAB程序,拟合出不同锚杆排列方式和不同的第一排锚杆支点位置对应的桩身最大位移的曲线函数,并用单纯形法计算出最优的锚杆间距和第一排锚杆的支点位置.提出深基坑多支点桩锚支护结构中支点的最佳分布形式.
Taking into consideration the load application position on top of excavation pit and first of all the anchor arrangement, the maximum displacement of piles is found with Lizheng software for an actual practice, a MATLAB program is compiled to fit a curve function of the maximum displacement of piles corresponding to different anchor arrangement modes and different support location of the first-row anchor, and finally, the simplex method is used to calculate the optimal anchor spacing and the support location of the first-row anchors. An optimum distribution mode of pivot in deep-excavation multi-pivot pileanchor structure is put forward.
