“635”水利枢纽大坝心墙防渗土料分散性鉴定及改性试验研究

Dispersion appraisal and modification analyses of the impervious soil materials for the core wall of the dam of “635” water control project

摘要: 通过大量试验分析 ,鉴定“6 35”大坝心墙防渗土料分别为非分散性土和过渡性土 ,并针对其存在的潜在分散性进行了多方案的改性试验研究 ,为认识和解决土料分散性工程问题提供了全面、可靠的科学依据。

Abstract: This paper presents the results of a great deal of tests, which show that the impervious soil materials for the core wall of the dam of “635” water control project are either nondispersive soil or transitional soil. The paper also includes analytical results of the potential dispersive property of the soil materials of the dam through multipleoptional modification tests, these analytical results provide comprehensive and reliable references for use of dispersive soil materials in construction of water control project.
