摘要
复合锚固桩是新型的地基加固技术,能够以和直桩几乎相同的成本布置斜桩,提供良好的水平承载力。通过对不同倾斜角度、不同组合方式的复合锚固桩进行数值模拟,探讨了复合锚固桩水平承载力与倾斜角度之间的关系,结果表明:倾斜桩的存在能够显著提高桩群的水平承载能力,相同组合方式的桩群极限水平承载力随倾角的增加基本呈线性变化,其中八字形斜-斜组合双桩的水平承载力超过斜-直组合桩。
The anchor-pile is a new foundation reinforcement technique,and it can provide a good level of horizontal bearing capacity,but inclined-pile's cost almost as same as vertical-pile's.Through the study of capacity of different angles and different combinations inclined anchor-pile groups,the results indicate that inclined anchor-pile can increasing the groups' horizontal bearing capacity.It also shown that there is linear relationship between the ultimate bearing capacity and the angle of inclined pile in the same combine mode,and the inclined-inclined pile group's ultimate horizontal bearing capacity is better than that of inclined-vertical group's.
