摘要
观测了大坝枢纽施工前期钻孔水位的分布情况,采用试算方法并结合有限元数值计算软件,分析了整个枢纽区渗流场的分布状况,并反演得出与实际工况相吻合的枢纽区岩体的渗透参数,从而为后期枢纽施工期和运行期渗流场的分布以及防渗和排水措施的布置提供计算依据。
In the early stage of dam foundation construction, observation of the distribution of drilling water level, using the method of trial calcu-lation and the finite element numerical simulation software, this paper analyzes the distribution of seepage field in the whole pivot area. It is found that the seepage parameters of the rock mass in the pivotal area coincide with the actual working conditions, which provides the basis for the dis-tribution of the seepage field and the layout of the seepage prevention and drainage measures during the construction and operation period.
