目前常用的地基处理方法有:垫层法、冲抓回填法和高压旋喷注浆法等。地基处理的目的是指提高软弱地质地基的承载力,保证软弱地质地基的稳定性;减少地基受到高水头时产生基础渗漏现象等。本文通过工程实例,介绍高压旋喷注浆法在病险水库大坝坝身防渗中的成功应用。
At present, the commonly used methods of foundation treatment are: cushion method, scratching and backfill method and high pressure rotary jet grouting method. The purpose of foundation treatment is to improve the carrying capacity of soft ground, to ensure the stability of soft geological foundation; to reduce the foundation caused by high head when the basic leakage phenomenon. This paper introduces the successful application of high-pressure rotary jet grouting method in seepage prevention of dam of dam in dangerous reservoir through engineering example.
