针对一种新型围桩-土耦合式抗滑结构,基于桩土耦合的假定,给出了耦合刚度的计算式,并分析耦合刚度与桩数、围桩间距、桩径等变化关系,分析得出刚度随桩间距、桩径、桩数增大而增大,为进一步讨论布置合理性,引入耦合结构的等效半径、耦合效能利用程度来进行分析,结果表明:采用选用桩数为6,围桩间距为3~5倍桩径组成的平面型式较为合理.其研究成果为建立这种新型抗滑结构的设计理论提供依据.

According to a new type of surround-pile-soil coupling anti-slide structure,based on the assumption of coupling of piles and soil,the coupling stiffness calculation formula is given,and the coupling stiffness change rule among pile number, pile spacing,pile diameter is analyzed. The result shows that stiffness increases with the increasing of pile spacing,pile diameter,pile number. To have a further discussion on the rationality of the arrangement,it is analyzed by using the equivalent radius and utilization degree of the coupling structure. The results show that using six piles,enclosing for 3 to 5 times the pile diameter,the pile spacing of plane model is more reasonable. The results of their research will provide a basis for the theory of the establishment of this new type of anti-slide structures.
