对于软基处理,许多工程实践中成功地应用了碎石桩、袋装砂井、超载预压、深层搅拌法等各种方法,结果表明效果是良好的。粉体搅拌桩法是深层搅拌法中的一类,该法就是在桩体范围内对软土进行改良加固以提高其强度和承载力,通常所使用的材料有水泥、石灰粉等。我们曾对汕头某地的软土进行了水泥改良效果的室内试验,本文介绍试验结果和初步分析,希望能起到一定的参考作用。 For soft foundation treatment, many methods such as gravel piles, packed sand wells, overload preloading, and deep mixing methods have been successfully applied in many engineering practices. The results show that the results are good. The powder mixing pile method is a kind of deep mixing method. The method is to improve the strength and bearing capacity of the soft soil in the range of the pile body. Commonly used materials include cement, lime powder and the like. We have conducted an indoor test of the cement improvement effect on the soft soil of a certain place in Shantou. This paper introduces the test results and preliminary analysis, hoping to play a certain reference role.
