摘要
Abstract
The high-pressure jet grouting features little impact on dam structure, simple construction and lower construction cost.It is one effective measure to prevent seepage and reinforce the hazard and defect dams.In the hazard elimination and reinforcement of Qinghai Wenquan reservoir , the foundation with yellow and silty sand is treated by the high-pressure grouting technology through application of advanced equipment and technology .The jet scheme and construction parameters are controlled and determined by site test and construc-tion technology.As high elevation, lower temperature and complicated geological conditions in the plateau region as well as the core being taken at 28 d after hole being grouted is in liquid plastic because of the high water content of the soil layer , the setting time is extended to 120 d after analysis and study and the expected result is achieved .关键词
