摘　　要：分析目前地下连续墙施工稳定液的现状,简要叙述聚合物溶液的性能特点,为适应当前地下连续墙施工成槽的需要,采用优选法研制了一种新型地下连续墙稳定液——聚合物溶液,并且与目前应用的细分散泥浆进行性能对比,显示出极大的优越性。这种稳定液能够满足极松散的流砂层和较软弱土层,可用于泥浆无力阻止塌方的槽段,或者用于处理已塌方的槽段施工。最后,探讨了聚合物溶液的护壁作用机理,为新型地下连续墙施工稳定液的研制提供理论依据。Current situation of construction stabilizing fluid for underground diaphragm wall is analyzed. Characteristic property of polymer solution is fully discussed. Optimum seeking method is used to study a new kind of construction stabilizing fluid for underground diaphragm wall-polymer solution. This solution is compared with slurry solution and displays its superiority-can meet the requirements of extremely loose floating sand layers, soft soil layers, and construction sections where slurry can＇t resist collapse, or collapsed construction section. Finally, the mechanism of protecting hole wall of polymer solution is discussed. It provides academic basis for the develooment of this new kind of construction stabilizing fluid for underground diaphragm wall.
