1·Then the measures of slot concrete cutoff wall were taken to the dam of Yongji reservoir.

同年开始了除险加固工程，对永记水库的防渗问题采用沟槽混凝土防渗墙处理。

2·As a new material for cutoff wall, plastic concrete was popularly used to reinforce the dike of the Yangtze River.

塑性混凝土作为一种新型的防渗墙墙体材料，在长江堤防防渗墙工程中得到了普遍的应用。

3·It is a must to add various additives in wall materials to meet different cutoff requirements against the cutoff wall's functions.

针对防渗墙所起作用的不同，墙体材料中需添加各种外加剂以满足不同防渗标准的要求。

4·These new technologies and methods basically represent the advanced level in the cutoff wall construction technology in China at present.

这些新技术、新方法代表了我国当前防渗墙施工技术的先进水平。

5·The test results show that soil concrete can satisfy the demands of cutoff wall in aspects of extensive deformation and seepage prevention.

试验表明，塑性混凝土能满足防渗墙良好的变形和防渗性能的工程设计要求。

6·The effect on seepage is small when the opening of cutoff wall crack is less than0.3cm themaximum relative water head at the bottom of lower core wall is only2.02%.

防渗墙出现裂缝开度小于0。 3cm时，对渗流场的影响不大，防渗墙下游心墙底部最大相对水头值仅为2。 02%；

7·For plastic concrete, due to its stronger adherence to sand and stone base and its lower elastic modulus, and its better deformation performance, it is used in cutoff wall.

塑性混凝土与砂石地基结合性好，弹性模量低，用作防渗墙具有较好的变形性能。

8·The dam cutoff wall is one of the underground hidden projects. Due to the construction technique and quality control, the quality detection is restricted by a variety of factors.

大坝截渗墙属于地下隐蔽工程，由于施工工艺及质量控制等原因，其质量检测受多种因素制约。

9·After accomplishment of the construction of cutoff wall, water pressure tests and quality inspection were conducted, and the results indicate that the dam meets the anti-seepage request.

防渗墙施工结束后，进行压水试验和质量检查，满足主坝防渗要求。

10·According to the seepage problems of Longhuai dam body and its geological conditions, the plastic concrete cutoff wall seepage was adopted to obtain better effect after scheme comparison.

龙怀水库坝体存在渗漏问题，根据工程地质条件通过方案比选，采用塑性砼防渗墙防渗，防渗效果较好。
