Abstract

Compressibility of strong and structurally disturbed rocks is determined for predicting land subsidence and stability during operation of transport machines. The plate-bearing tests are carried out on a large bench tester at different normal pressures and different densities of strong overburden rocks. The method to estimate deformability of strong overburden rocks using a plate and a station rod is described. The results were used to assess passability of transport machines during damming, and for the damp stability calculation.

运输机械运行过程中坝体和堆积场强覆盖岩的变形

摘要为预测运输机械运行过程中的地面沉降和稳定性，确定了结构扰动强岩体的压缩性。在大型台架试验机上进行了不同法向压力和不同密度下的强覆盖岩板承试验。本文介绍了利用板杆法估算强覆盖岩层变形能力的方法。结果被用来评估运输机械在筑坝过程中的通过性，并用于阻尼稳定性计算。
