前言随着国家对西部的开发以及基础设施建设的大力投资,在岩溶地区建设的公路桥梁越来越多,通常对这些地区的基础设计主要以嵌岩桩为主。随着计算机技术的进步及数值计算方法的发展,对非线性组合问题都具有明显的优势,ANSYS是现在岩土工程界使用最普遍的有限元分析和计算软件。本文基于复杂的溶洞地质情况,并在其上采用嵌岩桩,通过ANSYS数值模拟计算,对岩溶发育区溶洞嵌岩桩的承载特性的影响进行研究结果,能使基桩设计达到优化的目的。
Introduction With the state’s vigorous investment in the development of the western region and infrastructure construction, more and more highways and bridges are being built in the karst areas. The foundation design of these areas is mainly dominated by rock-socketed piles. With the development of computer technology and the development of numerical methods, it has obvious advantages for nonlinear combination problems. ANSYS is the most common finite element analysis and calculation software used by geotechnical engineering. Based on the complicated geological conditions of the karst cave and using the rock-socketed pile on it, the effect of the rock-socketed pile’s bearing capacity in the karst development zone is studied through the ANSYS numerical simulation. The design of the pile can be optimized.
