摘要
Abstract
In order to improve the physical and mechanical properties of shallow and geologically defective rock masses,enhance their uniformity,integrity,and impermeability,a large amount of consolidation grouting and curtain grouting have been carried out in the dam site area of Yinjiang Hydropower Project.To ensure the con-struction quality of grouting engineering,comprehensive geophysical techniques such as single hole acoustic wave method,borehole panoramic imaging,and water pressure test were used to comprehensively detect and e-valuate the grouting quality.The application results show that comprehensive geophysical techniques such as using single hole acoustic wave method to compare and analyze the characteristic values and changing trends of rock wave velocity before and after grouting,observing the development of rock structural planes and cement stone filling in the borehole wall through panoramic imaging,and analyzing the permeability of rock mass through water pressure test can comprehensively evaluate the construction quality of grouting engineering and provide a basis for the acceptance of concealed engineering.关键词
