【摘要】：国道318线在四川境内长约1294公里,沿线穿越众多复杂地形,呈规模的边坡处治工程数量远高于西部其他地区。但对于沿线地区边坡工程的总结研究相对较少,不利于对既有处治技术的推广。因此,本文在四川省公路边坡管理系统的支持下,对沿线区域典型边坡的工程地质条件、典型破坏形式、边坡特征因素以及典型加固处治措施进行了统计归纳、分析评价；结合对边坡的稳定性验算,探讨了本地区典型公路边坡处治技术的适宜性,其主要研究工作如下：(1)对国道318线四川境内沿线的地质条件进行了调查研究,并在地形地貌、地质构造以及环境气候综合分析基础上,提出将沿线研究区域分成两种典型地区,即：深切高山峡谷区及浅切平原丘陵区,同时指出了不同地貌分区之间,由于海拔高程、河谷切割、气候变化以及岩性、构造的主要差异。(2)在四川省公路边坡管理系统的支持下,搜集了沿线区域223处边坡工程的详尽信息,确定以边坡破坏形式(即崩塌、滑坡、错落、坍塌)、边坡特征因素(即岩性、坡高、坡度)以及加固方案(即挡墙、抗滑桩、锚杆、锚索)为三大对象,通过对搜集的相关数据进行分析研究,总结了沿线区域边坡工程的典型破坏形式及针对性的加固方案。(3)本文以成南高速公路K73段边坡工程完整施工过程为例,详细分析研究了国道318线在川东区内典型岩质公路边坡施工监测控制的方法。(4)针对川西区国道318二康段K2794岩质边坡处治典型工程,采用EMU岩质边坡处理软件,对边坡工程进行了稳定性验算,分析评价了工程加固措施的适宜性。(5)针对川西区国道318线海子山至竹巴笼段K303土质边坡滑坡及国道318线海子山至竹巴笼段波戈溪隧道进口土质边坡处治工程进行了稳定性验算及处治技术评价分析。
[Abstract]:National Highway 318 in Sichuan Province is about 1294 km long, along the way across a number of complex terrain. The number of slope treatment projects on a scale is much higher than that in other western regions. However, the summary and study of slope engineering along the line is relatively few, which is not conducive to the promotion of existing treatment technology. With the support of Sichuan Provincial Highway Slope Management system, this paper makes a statistical analysis of the engineering geological conditions, typical failure forms, slope characteristic factors and typical reinforcement and treatment measures of typical slopes along the route. Analysis and evaluation; Combined with the stability check of the slope, the suitability of the treatment technology of the typical highway slope in this area is discussed. The main research work is as follows: (1) the geological conditions along Sichuan Province along National Highway 318 are investigated and studied, and based on the comprehensive analysis of topography, geomorphology, geological structure and environment and climate. The study area along the route is divided into two typical areas: deep mountain canyon region and shallow cut plain hilly area. At the same time, it points out that the valley is cut between different geomorphologic zones due to elevation. With the support of Sichuan highway slope management system, the detailed information of 223 slope projects along the highway is collected. It is determined that the failure form of slope (that is, collapse, landslide, dislocation, collapse), slope characteristic factors (that is, lithology, slope height, slope degree) and reinforcement scheme (i.e. retaining wall, anti-slide pile, anchor rod, anchor cable) as three objects. Through the collection of relevant data analysis and research. This paper summarizes the typical failure form of the slope engineering along the line and the targeted reinforcement plan. 3) this paper takes the complete construction process of the slope engineering of the K73 section of Chengnan Expressway as an example. The method of monitoring and controlling the construction of typical rock slope of National Highway 318 in East Sichuan is analyzed and studied in detail, aiming at the typical project of K2794 rock slope treatment in Erkang section of National Road 318 in Western Sichuan. The stability of slope engineering is checked by EMU software. The suitability of reinforcement measures is analyzed and evaluated. Based on the slope landslide of K303 soil slope of Haizishan to Zhubagong section of National Road 318 in Western Sichuan and the treatment project of imported soil slope of Bogoxi Tunnel in Hizishan to Zhubagong Section of National Highway 318, stability check calculation and treatment are carried out. Technical evaluation and analysis.
