【摘要】 项目所在场地地质条件复杂,软土、岩溶发育、不良地质作用强烈,评定为抗震不利地段。如何进行合理的基础选型是本项目的重点难点。介绍了基础选型的过程,断桩的处理,总结出溶洞、土洞的处理方法。完工后测量的沉降变形量在规范要求范围内,项目的经验可以为今后类似场地的工程提供参考。更多还原

【Abstract】 The location of the project is complicated and the development of soft soil,karst and adverse geological actions are strong. The location is rated as antiseismic area. How to choose a reasonable foundation is the key and the point of the project. The process of the selection of the foundation,the treatment of the broken piles were introduced,and the method of dealing with soil cave and karst cave was summarized. The deformation measurement after the project completion met the requirement of the code. The experience of the project can provide a reference for the projects in the similar site.更多还原
