Abstract : in this paper , the application of splitting grouting method to danger removal and dam reinforcement in pishihang irrigation district , is illustrated and the engineering effect is introduced too 摘要:文章介紹劈裂灌漿法在淠史杭灌區(qū)堤壩除險(xiǎn)加固過(guò)程中的應(yīng)用和取得的效果。
Hereby , a study on the mechanical genesis , rock mass quality and engineering effect of the complicated rock mass is very important . base on site investigation and abundant past achievement , we carefully studied it and draw some conclusions 因此,研究右岸復(fù)雜巖體的成因、巖體質(zhì)量以及工程效應(yīng)對(duì)壩型的選擇及巖體的合理利用具有重要的意義。
Based on the systematic study on the coal - bearing strata in the dam region of some hydraulic key project , southwest of china , the paper disclosures the distribution of the discarded caves , analyses the engineering effects of the existence and the deformation of the discarded coal caves during the construction of the hydraulic key project and running of it 摘要通過(guò)對(duì)西南某水利樞紐工程壩區(qū)煤系地層的系統(tǒng)研究,揭示了在壩區(qū)左右岸煤洞的展布特征,結(jié)合工程,分析了煤洞的存在及其變形的工程效應(yīng)。
In the last part of the thesis a study of engineering effect about the complicated rock mass was done base on a numerical simulation and the engineering geological condition in the dam site . numerical simulation result reflect several disciplinarian of stress - distortion action in the right bank slope . firstly , today ' s right bank stress field mainly is grave stress field 在上述研究工作的基礎(chǔ)上,通過(guò)對(duì)右岸巖體應(yīng)力?形變作用的有限元數(shù)值模擬分析,表明:右岸壩基巖體的現(xiàn)今應(yīng)力場(chǎng)主要是在自重應(yīng)力場(chǎng)的基礎(chǔ)上,河谷下切應(yīng)力、分異的應(yīng)力場(chǎng)。
