地下连续墙施工中泥浆的调配研究

Research on Confecting the Mixed-Mud in Underground Continuous Wall

针对地下连续墙施工中对泥浆指标参数的控制调整而使现场泥浆达到较优性能的配比的复杂问题,采用赋值参数应用到泥浆比重的计算公式,得到关于加水稀释比重的经验公式。同时,使用马鞍山公园站地下连续墙现场泥浆做试验,以验证此经验公式的可行性及添加羧甲基纤维素(CMC)对粘度影响的一般规律。从而引导泥浆以达到较优性能,对类似工程实践具有一定的借鉴和指导意义。

Based on the construction of the complicated problem of underground continuous wall of mud parameter, which controlled and adjusted to achieve superior performance of the proportion, used assignment parameter applied to the mud weight calculation formula, it got about water-dilution proportion of experience formula. At the same time, it used the Ma-An-Shan park station of underground continuous wall field mud to do the test of verify the feasibility of the empirical formula and the adding of Carboxyl Methyl Cellulose (CMC) on viscosity influence the general rule. Guided the mud to achieve a superior performance, that is similar to engineering practice had certain reference and guidance.
