本文介绍针对不同地质状况进行实验室泥膜模拟试验,确定不同地质条件下形成泥膜所需泥浆配比方案,制订泥水舱泥浆性状指标值控制界限,严格泥水体系各系统的运行与管理,始终保持掌子面泥膜处于良好状态,保障泥水盾构隧道施工安全。
In this paper, laboratory simulation experiments for different geological conditions were carried out to determine the mud proportioning scheme for mud film formation under different geological conditions. The mudflat muddy performance index value control limits were formulated and the operation and management of each system of muddy water system was strictly followed. Keep the clay film in good condition and ensure the safety of shield tunnel construction.
