岩溶地区桥涵工程桩基施工问题及预防措施分析

Analysis on Pile Foundation Construction Problems and Preventive Measures of Bridge and Culvert Engineering in Karst Areas

岩溶是地表水和地下水对可溶性岩石,如石灰岩、白云岩、石膏等所进行的以化学溶解为主的地质作用和它所形成的地貌,一般以隐藏的形式出现,对桩基施工有较大的负面影响。基于此,文章针对因岩溶地区地质复杂,影响桩基质量因素较多的现状,分析岩溶地区桩基常见质量问题,为确保桩基质量,对岩溶地区桩基施工各阶段常见问题及预防措施展开细化分析,提出岩溶地区桩基施工注意事项,以供参考。

Karst is the geological process dominated by chemical dissolution of soluble rocks such as limestone,dolomite and gypsum by surface water and groundwater, and the landform formed by it. It generally appears in a hidden form and has a great negative impact on pile foundation construction. Based on this, this paper analyzes the common quality problems of pile foundation in karst areas due to the complex geology and many factors affecting the quality of pile foundation in karst areas. In order to ensure the quality of pile foundation, the common problems and preventive measures in each stage of pile foundation construction in karst areas are analyzed in detail, and precautions in pile foundation construction in karst areas are put forward for reference.
