【摘要】:本文以撫順發(fā)電有限責任公司廠區(qū)地質(zhì)災害評估為工程背景,針對該項目進行深入系統(tǒng)研究。本文介紹了該研究區(qū)內(nèi)的區(qū)域地質(zhì)環(huán)境及水文地質(zhì)特征,在此基礎(chǔ)上對其地質(zhì)災害現(xiàn)狀進行評估,并采用灰色理論對撫順發(fā)電有限責任公司基礎(chǔ)變形進行預測分析。最后,采用拉格朗日元法對該研究區(qū)進行數(shù)值分析,,以研究其變形過程中應力變化及發(fā)展趨勢。在此背景之下,本文主要進行以下幾個方面的工作: (1)收集資料及現(xiàn)場調(diào)查,根據(jù)該項目的研究需要,對該研究區(qū)地質(zhì)環(huán)境資料及水文地質(zhì)特征資料進行收集,并采用巖土工程勘察方法對該地區(qū)進行實地勘察。 (2)根據(jù)收集資料及勘察資料對該地區(qū)進行初步評估,對該研究區(qū)地質(zhì)災害現(xiàn)狀給出初步評價。 (3)在研究區(qū)布置沉降觀測點,得到沉降發(fā)展趨勢。采用灰色理論對其進行分析。經(jīng)過分析,在2010年、2011年兩年時間里,撫順電廠廠區(qū)內(nèi)建筑物基礎(chǔ)變形將超過規(guī)范要求最大值。在灰色理論分析中只考慮了沉降對廠區(qū)建筑物基礎(chǔ)的影響,但伴隨露天礦采煤過程,撫順電廠廠區(qū)伴隨著水平位移變化。水平位移變化也是該廠建筑物產(chǎn)生破壞的原因。 (4)利用數(shù)值模擬軟件,采用拉格朗日元法對該研究區(qū)進行數(shù)值模擬,計算是在理論研究的基礎(chǔ)上對現(xiàn)狀變形進行分析,并將計算結(jié)果與監(jiān)測資料進行對比,來驗證計算模型和參數(shù)選擇的正確性,從而來推算未來西露天礦開采對撫順發(fā)電有限責任公司廠區(qū)穩(wěn)定性的影響。 (5)經(jīng)過數(shù)值模擬分析,得出從2002年至2017年,研究區(qū)的水平位移與垂直位移的變化情況,并通過計算得到塑性區(qū)以分析該區(qū)域造成地質(zhì)災害的原因。 (6)考慮在地下水徑流與非地下水徑流兩種工況下,采用數(shù)值模擬軟件對該研究區(qū)的邊坡穩(wěn)定性進行分析。
[Abstract]:Based on the engineering background of the geological hazard assessment of Fushun Power Generation Co., Ltd, this paper makes a deep and systematic study on the project. This paper introduces the regional geological environment and hydrogeological characteristics in the study area, on the basis of which the present situation of geological hazards is evaluated, and the foundation deformation of Fushun Power Generation Co., Ltd is predicted and analyzed by grey theory. Finally, the Lagrangian element method is used to study the stress variation and development trend in the study area. In this context, this paper mainly works on the following aspects: 1) collecting data and field investigation, according to the research needs of the project, collecting the data of geological environment and hydrogeological characteristics of the study area, and using geotechnical engineering survey method to carry out field investigation in this area. 2) based on the data collected and the survey data, the preliminary evaluation of the present situation of geological hazards in the study area is given. 3) the settlement observation points are arranged in the study area, and the development trend of settlement is obtained. Grey theory is used to analyze it. According to the analysis, in 2010 and 2011, the deformation of the building foundation in Fushun power plant will exceed the maximum value required by the code. In the grey theory analysis, only the influence of settlement on the building foundation in the plant area is considered, but with the coal mining process in the open pit, the horizontal displacement changes in the plant area of Fushun Power Plant. The change of horizontal displacement is also the cause of damage to the building. 4) using numerical simulation software and Lagrangian element method to simulate the study area, the present deformation is analyzed on the basis of theoretical research, and the calculated results are compared with the monitoring data. In order to verify the correctness of calculation model and parameter selection, the influence of mining on the plant stability of Fushun Power Generation Co., Ltd in the future can be calculated. 5) through numerical simulation and analysis, the variation of horizontal and vertical displacements in the study area from 2002 to 2017 is obtained, and the plastic zone is calculated to analyze the causes of geological disasters in this area. 6) considering the groundwater runoff and non-groundwater runoff, the slope stability of the study area is analyzed by numerical simulation software.
