PHC管桩在基坑支护结构中的应用

Application of PHC Pipe Piles in the Retaining and Protection Structure for Excavations

PHC管桩用作基坑支护挡土结构,主要承担水平荷载,作受弯构件用,尚缺乏设计分析和工程积累。在此背景下,归纳分析了PHC管桩用作基坑支护挡土结构的设计要点,结合工程实例,介绍PHC管桩在基坑支护结构中的应用关键,实践表明,PHC管桩应用取得了基坑支护的预期效果。

There is hardly neither design analysis nor engineering accumulation in the application of PHC pipes used in the retaining and protection structure for excavations to bear the horizontal load as a flexural member. Based on this background, the key design points of PHC pipes used in the retaining and protection structure for excavations are summed up and analyzed. The application discussion on PHC pipe piles in the engineering of excavations is introduced combined with a project example, and the expected effect on the retaining and protection structure for excavation has been acquired.
