大面积的采空区给城市的建设带来极大的不利影响,大多数建筑物在建设前需要对采空区进行回填、灌浆等人工地基处理,造价非常高,因此需对采空区场地的稳定性做出正确的评价。基于Excel的VBA程序,根据相关规范公式编制了针对煤矿采空区地基稳定性评价的计算程序,该程序能对拟建场地的多点、多区域进行快速计算,得到最大残余沉降、曲率、倾斜、水平变形、水平移动等参数,根据这些参数进而能够准确地绘制出各种等值线,实现地基稳定性的正确评价。
Large area of goafs to the construction of the city has a tremendous adverse impact, most of the buildings in the construction of the need to carry out backfilling, grouting and other artificial foundation treatment, the cost is very high, so the need to mined area venues The stability of the correct evaluation. Based on the Excel-based VBA program, a calculation program for the evaluation of foundation stability of coal mined area is compiled according to the relevant rules and formulas. The program can quickly calculate multi-site and multi-area of the proposed site and get the maximum residual settlement, curvature, , The level of deformation, horizontal movement and other parameters, according to these parameters and then be able to accurately draw a variety of contour lines, to achieve the correct evaluation of the stability of the foundation.
