【摘要】：针对高桩码头岸坡设计中的稳定性问题,对镇江港某高桩码头岸坡建立有限元模型进行分析.在高桩码头的岸坡设计中,通常没有考虑桩基的抗滑作用,所以同时建立了无桩和有桩的码头岸坡模型,进而对比分析高桩码头中桩基对岸坡稳定性的作用,从而为高桩码头岸坡设计提供依据.土体的强度准则选用的是与Mohr-Coulomb匹配的Dracker-Prager准则,运用有限元强度折减法进行计算.研究结果表明:高桩码头中桩基的存在对岸坡稳定性能起到一定的抗滑作用,但是岸坡设计时,桩对岸坡抗滑作用必须降低到规范以下,否则桩基会因为承受过大的水平推力而发生破坏.
[Abstract]:In view of the stability problem in the slope design of high pile wharf, the finite element model of the bank slope of a high pile wharf in Zhenjiang Port is analyzed. In the slope design of high pile wharf, the anti-skid effect of pile foundation is usually not considered. At the same time, the bank slope model of wharf without and with piles is established, and then the effect of pile foundation on the stability of bank slope in high pile wharf is compared and analyzed. Therefore, it provides the basis for the design of bank slope of high pile wharf. The strength criterion of soil is Dracker-Prager criterion matched with Mohr-Coulomb. The finite element strength reduction method is used to calculate. The results show that the existence of pile foundation in high pile wharf plays a certain role in the stability of bank slope, but in the design of bank slope, the anti-slide effect of pile on bank slope must be reduced below the standard. Otherwise, the pile foundation will be destroyed by excessive horizontal thrust.
