摘　　要：遮帘式支挡结构是由板桩、遮帘桩及拉杆组成,适用于山区道路、大型水利工程、城市深基坑开挖等。采用数值计算方法分析了遮帘式支挡结构与常规支挡结构的差别,遮帘桩与板桩墙间距对遮帘效果的影响及其荷载传递机理。The barrier structure is consisted of sheet piles,barrier piles and tensioning bolts.It is applied to be the supporting or retaining structure in construction of mountainous road,large hydroproject and deep foundation pit excavation.The structural differences between the barrier structure and the traditional retaining wall,the influence of the spacing between the sheetpile and the barrier and the load conducting mechanism of the barrier structure are analyzed with numerical calculation.
