Analysis On Stability Of High Filled Slope

The high filled slope is artificial slope,which is one of the most basic geological environments in human engineering activities. With the development of the resources energy projects and the infrastructure construction, China has become the largest engineering construction scale country in the world. All kinds of water conservancy and hydropower facilities, mines, ports, energy engineering and petrochemical engineering are in the process of development and construction.Many high filled slopes are formed in the period of construction or operation. The deformation and failure of slope is a long-term changing process.The stability of slope is affected by many kinds of factors that can be mainly divided into internal factors and external factors. The internal factors include the types and nature of soil, slope forms, groundwater,etc. The external factors include vibration effect, climate condition, weathering, slope vegetation, human engineering activities, etc. In some certain engineering geological condition, the factors of influence make different contribution to the slope stability.Some factors have big influence on the slope stability, and some have small influence. The high filled slope stability is closely related to human lives and property. So, how to make correct analysis of the stability of high filled slope to reduce the harm caused by failure of slope to the minimum is the problem that the geotechnical engineering scholars and engineering design personnel must consider.This paper is to make finite-element analysis of the high filled slope of wulong western valley belonging to oil refining reconstruction project in Changling branch company of the China Petroleum and Chemical Corporation.Then, combining with the monitoring results,it can analyze the stability of the high filled slope.Meanwhile, this paper analyzes the sensibility of the influence factor to the stability of slope with the high filled slope as an example. The main research contents of this paper are as follows:1. Based on the domestic and foreign research data, the research status is fully understoodo Also, the development history of the slope stability analysis method is reviewed comprehensively, including analyzing characteristicses of the slope stability analysis methods. 2. The engineering characteristicses of high filled slope are summarized, including the slope failure forms and the factors of influence.3. Through the soil structural model combining with the boundary conditions of high fill slope, the stability of the high filled slope of wulong western valley high filled slope is analyzed using the functiongs of finite element software with the physical and mechanical parameters. Besides, the value of settlement and deformation is concluded.4. The sensibility of the influence factor to the stability of slope is analyzed with the high filled slope as an example and the sensitivity value corresponding to different factors of influence is gotten with the purpose of providing references for the designs of the same slopes。5.The theoretiacl rusults are compared with the the monitoring results to analyze the stability of the high fill slope。...
