基于动态勘察理念的圣中水库大坝动态设计修正

Dynamic correction of dam design of Shengzhong reservoir based on the concept of dynamic prospecting

以点带线、带面的传统工程地质勘察方法不能获得全面和深部的岩土体的物理力学参数和透水性能,从而带来了水库大坝的设计风险。依托重庆市江津区的圣中水库,扩展动态勘察理念,把大坝修建开挖过程中岩土体定性定量描述、二次强度试验和二次注水试验等作为动态勘察的延伸,获得了全面和深部的岩土体的物理力学参数和透水性能,实现了圣中水库大坝设计的动态修正,保证了大坝的顺利修建和水库的长久运营。

Because the traditional engineering geological prospecting method with point,line and surface cannot obtain physical and mechanical parameters and permeability performance of comprehensive and deep rock and soil,which brings risk to dam design.After the concept of dynamic prospecting has been extended,the qualitative and quantitative description,secondary indoor strength test,secondary water injection test and so on of rock and soil are used as extension of dynamic prospecting based on Shengzhong reservoir in Jiangjin District,Chongqing.Physical and mechanical parameters and permeability performance of comprehensive and deep rock and soil are obtained,which achieves dynamic correction of dam design of Shengzhong reservoir,ensuring the smooth construction of the dam and the long-term operation of the reservoir.
