| 摘 要： | 采用自行开发的ROCK MODEL程序建立了研究区三维地质模型，然后根据现场实际情况进行反演分析，确定矿体开采范围和岩土体物理力学参数；其次对塌陷坑现状进行流变分析；最后对二次塌陷进行弹塑性和流变计算，预测塌陷坑最终的发育范围，并提出相应防治措施.研究结果表明，塌陷坑在考虑流变情况下不会对外围公路产生影响，在二次塌陷情况下，会影响外围公路的安全运行，建议尽快进行处理.

| Abstract: | A 3D geological model in the study area with the ROCK MODEL software was developed.Then according to in-situ conditions,the range of orebody mining and the physical and mechanical parameters of rock and soil mass were confirmed by inversion analysis.The creep analysis of the pit actuality was done.The elas-plasticity and creep of the second collapse were computed,and the final range of the pit was forecasted.Also,corres-ponding control measures were advanced.The results demonstrate that the collapse pit wil... |
