【摘要】 准确评价各种岩体和结构面的力学强度,是工程地质勘察的一项重要工作,也是工作的难点。根据多年的工程实践,结合龙滩工程施工期开挖揭露的具体地质条件与地质问题,对龙滩工程岩体及其结构面力学强度参数的选取作了一些补充规定,并探讨了影响岩体和结构面的力学强度参数选取的各种因素。更多还原

【Abstract】 Accurately evaluating various mechanical strengths of rock mass and it′s structural planes is not only one of the important working contents of the geological survey but also the difficulty to the geological prospecting work. Based on engineering practice of many years and combined with the physical geological conditions and problems exposed in the period of the excavation construction of the Longtan project, this paper makes some additional regulations for the mechanical strength parameter selection for the rock mass and it′s structural planes in Longtan project. In addition, it discusses the various factors which have influenced on the parameter selection of the mechanical strengths of rock mass and it’s structural planes.更多还原
