【摘要】:黄玉川煤矿进场公路段,受人类工程活动的影响,出现路基沉降、塌陷、滑移、路面开裂等病害现象,致使交通受到严重影响,甚至使其完全中断。本课题是在对室内和野外工程滑坡资料的充分收集的基础上,来进行分析研究该进场公路段斜坡的工程地质条件的,主要研究了进场公路滑坡诱发因素和形成机理。诱发因素主要包括内在因素和外在因素两个方面,外在因素主要指地表地下的汇水情况,自然降雨气象情况,裂隙发育情况和排水措施不当等。内在因素则主要是指具备了产生滑动的坡体结构。在此基础上,重点研究了该滑坡的性质特征、形成机制、滑动类型、破坏模式、治理措施的研究。采用极限平衡分析的方法计算了滑坡的稳定性,采用FLAC3D软件对该段坡的稳定性和变形进行了数值模拟,对该滑坡进行了稳定性分析与评价,归纳总结,从而对该滑坡提出了有效的工程治理措施意见和建议。
[Abstract]:Due to the influence of human engineering activities, the roadbed settlement, collapse, slippage, pavement cracking and other diseases occurred in Huangyuchuan Coal Mine's approach highway section, which seriously affected the traffic. This subject is based on the full collection of landslide data for indoor and field engineering to analyze and study the engineering geological conditions of the slope in the approach highway section. This paper mainly studies the induced factors and formation mechanism of approach highway landslide. The induced factors mainly include internal factors and external factors. The external factors mainly refer to the water catchment situation of the ground surface and underground, the natural rainfall weather situation. The internal factors mainly refer to the slope structure which produces sliding. On the basis of this, the characteristics of the landslide, the forming mechanism, the sliding type and the failure mode are studied emphatically. The stability of landslide is calculated by the method of limit equilibrium analysis. The stability and deformation of the slope are simulated by FLAC3D software. The stability of the landslide is analyzed and evaluated. Therefore, effective engineering treatment measures and suggestions are put forward for the landslide.
