摘要
对马钢新区土坡稳定性进行了分析,确定该边坡整体上不稳定,根据坡顶张裂缝发育情况,推测该边坡可能发生圆弧型和平面型两种滑动破坏。根据土体力学强度室内试验结果有时与实际情况存在较大偏差的实际,结合本边坡已经发生圆弧型滑动破坏的情况,基于现场量测结果和计算边坡安全系数的条分法,对边坡的土体力学强度参数采用回归分析法进行了反分析,最后,根据土体的强度参数的试验结果和反演结果对边坡的安全系数进行计算,计算结果表明反演结果更为接近实际情况,可以作为加固方案设计的依据。
By the stability analysis for the soil slope in the new area, MaGang, it can be concluded that the slope is not safe. From the developing characteristic on the top of the slope, this slope may slide in circular and planar failure two types. Because there is the deviation between the real mechanics strength parameters and the result from the experiment sometimes, this paper calculates the mechanics parameters of the soils by the regress and back analysis methods, basing on the site measure and slice method for the calculation of the safety coefficient. At last, the safety coefficients of the slope are calculated based on the mechanics parameters from the experiment and back analysis two conditions. The calculation results show that the back analysis is more close to the reality, which can be used as the basis of the consolidation programmed design.
