摘要
根据岩溶地区红粘土层其状态一般为上硬下软的变化规律,基岩埋藏平均深度较浅,但起伏较大的地质特点,以及横向荷载作用下,单桩工作性状分析,论述了采用上大下小的嵌岩变截面桩的合理性。采用地基反力系数为常数进行分析,对桩径、变截面位置的初步拟定提出了依据,并通过有限元法对变截面桩的上、下段相互作用,嵌岩效应进行分析讨论。
Based on the changing regularity of the soft top and hard bottom adamicearth,this paper analyzes the working properties of single pile under a lateral load.It amplifies on the validity of the big end up non uniform pile embedded in rock.The basis for the diameter or the position of varying cross section is raised thorugh a finite element method with a constant coefficient of soil reaction.It also discusses the interreation between the upper and lower parts of the non uniform pile and the effect of embedding in rock.
