东阳市八面山项目边坡稳定性评价.docVIP

东华理工大学毕业论文 摘 要 PAGE PAGE 1 摘 要 本文根据东阳市八面山项目边坡工程岩土工程勘察资料，阐述了该工程的工程概况，自然地理概况，水文地质条件和边坡工程地质条件，给出边坡稳定性评价及治理措施建议。论文主要内容和取得认识如下： （1）分析项目区的自然地理条件，水文地质条件和工程地质条件。表明了该区场地环境类型为Ⅲ类，地层渗透性B类，场地土对钢结构具微腐蚀性，抗震设防类别为丙类。 （2）根据岩土层成因时代、岩性特征、岩体风化程度、物理力学性质差异等，研究区边坡划分为A、B、C、D、B-1五个区块，并分析了其存在的不良工程地质现象。 （3）分析表明了研究区有五处地质灾害点，均为滑移型浅层工程滑坡。 （4）开展边坡稳定性分析与评价。论文采用条块法计算各区边坡的稳定系数Fs，计算结果表明：A区块稳定系数为1.99—2.72，处于稳定状态；B区块稳定系数为0.92—1.18，处于不稳定至欠稳定状态；B-1区块稳定系数为1.01—1.03，处于欠稳定状态；C区块主要为构造带（F1），整体处于稳定状态；D区块稳定系数为2.57—3.19，处于稳定状态。 (5)针对稳定性评价结果，提出与其相适宜的治理措施。 论文取得的成果可以为该工程建设施工与地质灾害防治提供依据。 关键词：八面山； 边坡工程； 地质灾害； 工程地质； 评价； 东华理工大学毕业论文 ABSTRACT ABSTRACT According to the data of geotechnical engineering explore for slope engineering on Dongyang city Bamian mountain project, this paper expounds the general situation of the project , natural geography situation, hydrogeology conditions and the geological conditions of the slope engineering, evaluation on the slope stability and suggestion of effective control measures are given. Main contents and acquire result of this papers is as follows: (1)Analysised natural geographical conditions, hydrogeology and engineering geology conditions of the project area. Shows that the space environment type is Ⅲ class, permeability of stratum is B class, site soil have slightly corrosivity to steel structure, resist earthquake and categories of fortification for c class. (2)According to the formation age of layer, the characteristics of lithology, the weathering degree of rock mass, the differences between physical and mechanical properties,ect, slope in the study area is divided into five blocks: A, B, C, D, B - 1, and analyzes the adverse geological phenomena that probably existence in the area. (3)Investigate shows that there are five geology disaster point in the study area , all are engineering landslide that the type of shallow slip. (4)To carry out analysis and evaluatio
