马来西亚槟城二桥部分基础采用斜桩双承台,由于其采用斜桩基础,且桩基间距小于规范要求,沉降不方便计算。为控制其变形,需预估沉降值,通过有限元软件建立其中两个最具代表性的斜桩承台的空间模型,分为单承台和双承台两种情况,分析两种情况的沉降情况以及两承台间的相互影响,得出单承台和双承台两种情况下的沉降计算值以及变形情况,进而确定出双承台间的影响系数。同时比较桩身压缩量与总沉降的关系,结果表明沉降主要是由桩身压缩量引起,且总沉降满足要求。
Penang, Malaysia, the second bridge part of the basis of the use of inclined pile double cap, because of its use of inclined pile foundation, and the pile spacing is less than the specification requirements, settlement is not convenient calculation. In order to control the deformation, the settlement value needs to be estimated, and the spatial model of two of the most representative inclined pile caps is established by using finite element software. The two models are divided into single and double caps. Settlement and the interaction between the two caps to obtain the calculated settlement and the deformation under the two conditions of single cap and double caps and then determine the influence coefficient between the caps. At the same time, the relationship between the amount of pile compression and total settlement is compared. The results show that the settlement is mainly caused by the amount of pile compression, and the total settlement meets the requirements.
