摘　　要：桩板墙在土木工程领域应用较为广泛,但在粒状碎屑溜砂坡防治工程中的应用却不多。主要原因在于粒状碎屑溜砂坡的散体结构特征不同于一般的岩土体。首先介绍了目前一些常用的溜砂坡防治对策,指出他们存在的问题,然后根据溜砂坡的特点,推导出了砂坡土压力的计算方法,最后针对溜砂坡边挖砂坡脚边溜砂难题提出了一种解决方法。为溜砂坡灾害的防治提供了另外一种可供选择的方案。Nowadays,sheet pile wall has been widely used in the field of civil engineering. But it has little applications for the stabilization and protection of sand-sliding slope which composed by granular clast. The main reason lies in the structure＇s differences between general soil slope and sand-sliding slope. Common engineering measures for sand-sliding slope and their limita- tions were presented. Base on the sand-sliding slopers characteristic, a calculation method of sand slopers pressure was deduced,and an engineering measures was presented for solving the problem that the sand slides as the cut of slope toe. Thus, an optional design and construction technique of sheet pile wall was developed for sand-sliding slopers stabilization and protection.
