摘要
本文使用弹性支点法,通过实例分析、从综合考虑稳定、强度、变形的角度、讨论了深基坑排桩-单支撑支护结构支护点的优化问题,说明了单纯考虑桩身强度与稳定的不足,以及实际工程中优化的重要意义和可行性.
This paper discusses optimal design of bracing and upholded structure of deep foundation pit.In order to take the stability,strength and deformation of deep foundation pit synthetically into consideration the FEM(Finite Element Methold)of beams on elastic subgrade is applied to optimize the upholdihg points of single branch-piles deep foundation supporting structure.The paper states the shortcomings of considering only the stability of pit and illustrates significance and feasibility of the optimal design of examples intrue projects.
