金安桥水电站岩体变形模量参数的分析研究

The analysis of the rock mass modulus of deformation parameters in of the Jin’anqiao hydropower station

中国水能资源的丰富和开发程度较低的国情,决定了加快水电开发的迫切性。国内外一系列大中型水电工程的开发建设,存在的大量工程地质问题使人们逐渐认识到岩体力学参数选取的重要性。据有关资料显示,国际上大坝失事40%是由岩体力学参数选取不合理造成的,如法国的布泽(Bouzey)坝、美国的奥斯汀(Austin)坝等。结合金安桥水电站现场岩体变形模量及相关成果数据,与各种变形模量参数分析的方法,进行了变形模量与声波的关系研究,变形模量的经验估算法研究,变形模量的分形、分类研究。合理的变形模量参数的选取,是工程投资和安全风险博弈的岩体力学参数选取的重点。

Because the enriched and low degree of development of the national conditions of China’s hydropower resources,so decide to accelerate urgent hydropower development. With the domestic and foreign large and medium-sized hydropower project development and construction,the existence of a large engineering geological problems make people come to realize the importance of rock mechanics parameters selected. According to related statistics,40% of international dam failure is according to the rock mechanics parameters selected unreasonablely,Dam,such as France,Bouzey dam,the United States,Austin dam and so on. With Jin’anqiao Hydropower live rock mass deformation modulus,related outcomes data and various parameters of analytical methods,the article make the relationship research between deformation modulus and acoustic,experience estimation of deformation modulus and the fractal & classification research of deformation modulus. Reasonable selection of the modulus of deformation parameters,is the focus of investment and security risk game of rock mechanics parameters to select.
