小型预制桩用于SMW工法基坑围护结构的计算分析

Calculation Analysis of Minitype Prefabricated Piles in SMW Method to Brace the Pit

对以预制桩为劲性材料的某SMW工法基坑围护结构采用增量法进行计算分析,讨论中小型基坑中,以预制桩代替H型钢作为劲性材料,在预制桩结构强度和围护结构变形许可范围内,该工法基坑适宜的开挖深度、支撑数量。

With increment method, this paper analyze a pit engineering braced by SMW method adopting prefabricated piles to replace H-typed steel as stiff material. For small and medium pits using prefabricated piles in SMW method, the reasonable pit depth, the number of steel braces are discussed within the allowable structure strength and deformation.
