【摘要】 椭圆形支护结构通过合理选型可以成为以受压为主的支护结构,水泥土桩施工简单,经过适当咬合可起到止水帷幕作用,因此在开挖深度不大情况下,可优先采用椭圆形水泥土支护结构.根据某水泥土桩基坑支护工程的实践,以水泥土桩挡墙结构的承载力为控制条件,研究分析了椭圆形水泥土支护结构的优化选型方法,对椭圆形支护结构的工程应用具有一定的工程意义.更多还原

【Abstract】 An elliptical retaining structure can be the retaining structure mainly bearing the compressure force by reasonably selecting types. Cement-soil piles can be water-proof walls by adequately lapping, with the advantage of simple constructing. In case of shallow excavation, thereby, ellipse cement-soil retaining structures are adopted. In the paper, the optimum design method is researched according to the engineering practice of a foundation pit retaining project with the cement-soil pile retaining walls, on the controlling condition of the bearing of cement-soil pile retaining walls. It has certain engineering significance for the engineering application of elliptical retaining structures.更多还原
