摘要
Abstract
In order to ensure the safety and reliability of CFRD's plinth placed on the bank slope of completely weathered bedrock, this paper analyses four key technical issues, including the bearing capacity of foundation, the seepage control of foundation, the stability of plinth, and the differential settlement of plinth. With the engineering example of Vietnamese Tuyen Quang CFRD, some appropriate engineering measures were proposed, which include improving the bearing capacity of foundation, strengthening the connection between plinth and completely weathered bedrock, ensuring the seepage stability of foundation and setting plinth expansion joints in different bedrock junctions. The dam safety monitoring results show that the seepage volume of Tuyen Quang CFRD is small, and the deformation regularity of the dam is normal. By application of the engineering measures proposed in this paper, placing the plinth on completely weathered bedrock is safe and feasible.关键词
