一、前言水利水电工程经常遇到的工程地质问题是地基渗精,特别是砂性土的地基和土堤土坝更易发生诸如渗水、冒砂、管涌以及流土流砂等渗流破坏现象。据不完全统计,水利水电工程中有失事的,往往十之六七是与渗漏有关.为了解决地基和堤(坝)身渗漏,1990年5月我们在骆马湖南堤防渗加固工程中,应用射水法建造地下混凝土连续墙技术(以下简称射水法成墙技术。此项新技术的主要设备系从福建省引进),进行了工程性试验。试验结果表明,采用射水法成墙技术建造的地
I. Introduction The engineering geological problems frequently encountered in water conservancy and hydropower projects are infiltration of the foundations. In particular, the foundation of sandy soil and embankment earth embankment are more prone to such seepage, sand-collecting, pipe-filling and flow-sand flow seepage destruction. According to incomplete statistics, there are calamities in the water conservancy and hydropower projects, often related to seepage. In order to solve the seepage of foundation and dike bodies, in May 1990, , The application of water method to build underground concrete continuous wall technology (hereinafter referred to as the water law into wall technology. The main technology of this new technology introduced from Fujian Province), carried out engineering tests. The test results show that the use of water wall technology into the construction of the ground
