某永久边坡双排桩支护设计及应用

Design and application of double-row pile retaining structures in a permanent slope

门架式双排桩支护体系为超静定结构形式,具有较大的刚度,能够有效地限制支挡结构的变形。通过济南某小区永久边坡双排桩支护工程,介绍了双排桩支护设计方案,通过对该设计方案的计算分析和监测结果对比,表明双排桩支护体系较适于受到空间及耐久性要求的永久边坡支护工程,为北方地区具有较好应用前景的永久支护支挡结构,最后总结了双排桩支护设计特点,以供类似工程参考。

The double-row pile retaining structures is statically indeterminate system and has greater stiffness.It can effectively limit the deformation of retaining structures.Through the double-row pile support of a permanent slope in a community of Jinan,the design of double-row piles is presented.The calculation and analysis of the design schemes and comparison of the monitoring results show that double-row pile support system is more appropriate to the permanent slope support projects subjected to space constraints and durability requirements.The permanent support system has good application prospect in northern China.The design features of double-row pile retaining structures are summarized.It is helpful to similar projects.
