【摘要】：黃玉川煤礦進(jìn)場(chǎng)公路段,受人類(lèi)工程活動(dòng)的影響,出現(xiàn)路基沉降、塌陷、滑移、路面開(kāi)裂等病害現(xiàn)象,致使交通受到嚴(yán)重影響,甚至使其完全中斷。本課題是在對(duì)室內(nèi)和野外工程滑坡資料的充分收集的基礎(chǔ)上,來(lái)進(jìn)行分析研究該進(jìn)場(chǎng)公路段斜坡的工程地質(zhì)條件的,主要研究了進(jìn)場(chǎng)公路滑坡誘發(fā)因素和形成機(jī)理。誘發(fā)因素主要包括內(nèi)在因素和外在因素兩個(gè)方面,外在因素主要指地表地下的匯水情況,自然降雨氣象情況,裂隙發(fā)育情況和排水措施不當(dāng)?shù)�。�?nèi)在因素則主要是指具備了產(chǎn)生滑動(dòng)的坡體結(jié)構(gòu)。在此基礎(chǔ)上,重點(diǎn)研究了該滑坡的性質(zhì)特征、形成機(jī)制、滑動(dòng)類(lèi)型、破壞模式、治理措施的研究。采用極限平衡分析的方法計(jì)算了滑坡的穩(wěn)定性,采用FLAC3D軟件對(duì)該段坡的穩(wěn)定性和變形進(jìn)行了數(shù)值模擬,對(duì)該滑坡進(jìn)行了穩(wěn)定性分析與評(píng)價(jià),歸納總結(jié),從而對(duì)該滑坡提出了有效的工程治理措施意見(jiàn)和建議。
[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.
