Based on the direction of sources and the ratios of sandstone to formation of sedimentary rocks, together with the sedimentary structures and textures, paleocurrent direction and the characteristics of paleontology, etc., the planimetric maps of sedimentary facies of each stages in the studied area are compiled in order to recognized the extension of dominant facies and the evlotionary history of sedimentary environment, hi the stage of benxi and taiyuan, lagoon - tidal flat sediments are widespread in the area, and the deposits of estuary, lagoon and small delta in the northwest margin of ordos
以物源方向和沉積巖砂地比值為基礎，結合沉積結構構造、古水流方向及古生物特徵等，編制了研究區各期次的沉積相平面圖，以識別優勢相展布和沉積環境演化。本溪期和太原期研究區瀉湖?潮坪沉積分佈廣泛，西北緣發育河口灣、瀉湖及小型三角洲沉積。As to the tunnels of jinping hydroelectric power station in sicuan province, the thesis discusses how to reasonably consider the initial stress field when designing a large - scale tunnel with high initial stress and deep buried. first, by analyzing of the rock lab tests and discusses the feature of regional geomorphology. explains the production of initial stress field, analyze the initial stress of jinping hydroelectric power station ; second, using the fem, the paper creates the real model of region. according to the results of stress measurement point, by combining of ann and fem to decide the boundary condition, the paper calculates the initial stress field ; at last, the paper analyzes the influence of the initial stress field formed from different condition on the deformation and stress of the surrounding rock, and the main factor to influence the initial stress. on the basis of the former work, the author proposes some proposals, which will be helpful for studying and designing of the similar undergroun d engineering
首先從巖體的應力?變形的特性入手，並結合工程區域的地形地貌特徵，對巖體初始地應力場的形成做出解釋，結合錦屏水電站初始地應力的現狀提出了將地應力場進行分帶；然後建立整個工程區的實體模型，在地質分析的基礎上，以工程區右半部分為代表，參照實測點的初始地應力值，採用了神經網路與有限元相結合的方法反演了該區域的初始地應力場；最後模擬隧洞的開挖，通過計算比較分析了初始地應力場對處于不同應力帶內的隧洞圍巖穩定性的影響，在此基礎上提出了作者的建議，力圖為該類工程的研究設計工作提供有益的幫助。
