柳州银都大厦核心筒桩基础因场地岩溶发育极强，桩长差异极大，使长短桩应力与变形发生差异，为保证基础工程安全可靠，对桩基进行了三维有限元分析。计算结果说明，个别短桩的应力已超过混凝土的抗压强度，如对短桩进行的期脱空、后期加载并考虑其他有利因素，则桩的应力差异可趋于平缓。 The core tube pile foundation of Yindu Mansion in Liuzhou is very strong due to the karst development of the site, and the difference in pile length is very different, which makes the stress and deformation of long and short piles different. To ensure the safety and reliability of the foundation project, a three-dimensional finite element analysis of the pile foundation was conducted. The calculation results show that the stress of individual short piles exceeds the compressive strength of the concrete. For example, the short-term period of short piles, the late loading, and other favorable factors are taken into consideration, the difference in pile stress can be flattened.
