摘要:在岩土工程领域,双排桩的发展应用取得了很多成果。在滑坡和基坑工程中,尤其是剩余下滑力或岩土侧向压力特别大的工程案例中,双排桩更是发挥了其整体刚度大,变形位移小,桩身内力较单排桩明显下降的优势,对于双排抗滑桩,目前已经取得了很多的研究成果,但是还有一些问题没有形成统一的认识,桩间土对前后排桩的土压力计算、双排抗滑桩排距、桩径.桩间距以及桩间土土拱效应、桩土相互作用等对支护结构整体稳定性影响等问题。
Abstract: Many achievements have been achieved in the development and application of portal double row piles in the field ofgeotechnical engineering. Double row anti-slide piles are widely used in landslide and foundation pit engineering especially in engineeringcases that the residual pushing force or lateral pressure of rock and soil is extremely high. Double row piles have many advantages foeexample large overall stifiness,small deformation displacement, and significantly lower intermal fore of pile shaft than single row piles.Alot of research results have been achieved on double row anti-slide piles.However, there are sill some problems that do not form a unifiedunderstanding, such as the calculation of the earth pressure of the soil between piles on the front and back rows of piles, the row spacing ofdouble row anti slide piles, pile diameter, pile spacing, and the soil arching effect between piles on the overall stability of the supportingstructure.
