持续高强度填筑防渗土的质量控制

Quality control on anti-seepage earth material with sustainable high strength for dam filling

大隆水利枢纽一期大坝填筑工期短,强度大,土料控制要求高;料场分散,料场土料特性差异大,质量控制难度大。针对上述情况,从规划、实施、现场检验等方面对质量加以控制,从而确保防渗土填筑的质量。

So far as the construction of Dalong Water Control Project is concerned, the earth-rock fill dam in the first construction phase is filled with short construction period, high construction intensity and high requirement for the quality control on the filling material ; for which the borrow areas are decentralized with a large diversity of the characteristics of the earth materials, and then the quality of the earth material is difficult to be controlled. Under this circumstance, the quality control is made for all the aspects such as planning, construction, site testing ere, so as to ensure the filling quality of the anti-seepage earth material.
