摘　　要：针对复杂岩溶地质条件下厂房地基基础工程中基础选型、基础设计和实际施工中存在的问题,基于实际工程进行研究分析。根据场地内不同的地质情况,选择不同的地基基础型式;按照规范规定,对嵌岩桩逐桩进行施工勘察,以此作为桩基终孔依据;根据现场施工情况,综合考虑安全可靠、工程造价及施工便利等各项因素,解决了施工过程中出现的桩基护壁、溶洞处理、基底岩面凹凸不平等问题。Aiming at the problems in foundation selection,foundation design and construction of plant foundation engineering under karst geological conditions,an actual engineering project is analyzed.The foundation types are selected according to different the geological conditions in the site;according to the codes,construction survey is required for each rock-socketed piles,which is also the basis for the hole finishing of the pile foundation;according to the site construction conditions,the safety,reliability and project cost,construction convenience and other factors are considered comprehensively,the problems,such as pile foundation wall protection,karst cave treatment and rough and uneven base rock surface,are solved during the construction process.
