| 摘 要： | 处于岩溶强裂发育地区的柳州银都大厦基础，由于岩面起伏大，溶槽深，溶洞多，致使落在岩基上的长短桩长度差异最大达５５倍，引起桩的应力和变形差异过大，影响地基的安全与稳定。本文论述了用材料力学方法和有限元法计算长短桩的应力变形情况，对长桩变形量过大，短桩及桩顶承台板应力较集中，提出了处理建议。

| Abstract: | Linzhou Yindu Building lies on the foundation where karst intenselydevelopes. The surface of the karst undulates greatly , the katst slot is deep and there are many holes , so that the Max. length of piles on the karst foundation differs by 55 times. This induces big differrence in stress and deformation of piles. This article will introduce the calculation of the stress and deformation of long and short piles by using methods of mechanics and finit element . It also give the suggestion for solving the excessive deformation of long piles and for the stress of short piles , as well as supporting plank of upper piles. |
