摘　　要：三轴水泥土搅拌桩在SMW工法墙体中的应用已经相当成熟,其优良的垂直度和可控的桩间搭接宽度使其成为一种非常有效的地下结构施工方式。将其应用于深厚中密至密实砂层中作为止水帷幕,则是一种相对新颖的尝试。工程试验结果表明,在临近海域,深厚砂层采用三轴搅拌桩进行止水,是比较经济可行的方法。The application of three-axis cement soil mixing piles in SMW construction method walls has been quite mature.Its excellent verticality and controllable overlap width between piles make it a very effective underground structure construction method.However,applying it as a waterproof curtain in deep,medium dense to dense sand layers is a relatively novel attempt.The engineering test results show that using three-axis mixing piles for waterproofing in deep sand layers near the sea area is a relatively economical and feasible method.
