岩溶地区地质条件复杂且变化性较大,在这种地质环境下进行桩基施工,对施工技术和施工条件要求极为严格,这也是导致很多类似工程案例出现技术问题的主要原因。因此,在岩溶地区进行深桩基施工时,必须因地制宜,考虑到多方面的变量因素,以此制定出完善的施工计划以及技术管理措施,同时还要结合施工单位资质,找出深桩基施工过程中存在的技术薄弱环节,按照难以程度对施工列表进行编排,这样能保证施工项目按计划进行。本文基于上述问题,对岩溶地区深桩基施工的重点和难点进行了简要分析,并对施工过程中容易出现的不良影响因素进行了探讨,最后提出了深桩基施工的针对性技术,以期能为施工人员提供借鉴。
The geological conditions in the karst area are complex and changeable. Carrying out the pile foundation construction under such geological environment requires extremely strict construction technology and construction conditions, which is also the main reason causing technical problems in many similar engineering cases. Therefore, deep pile foundation construction in karst areas must be based on local conditions, taking into account many variables, in order to develop a sound construction plan and technical management measures, but also with the qualification of construction units to identify the construction of deep piles The process of the existence of technical weaknesses, according to the degree of difficulty to arrange the list of construction, so as to ensure that the construction project according to plan. Based on the above problems, this paper briefly analyzes the key points and difficult points of deep pile foundation construction in karst area, and discusses the unfavorable factors that are easy to appear in the construction process. At last, the paper puts forward the targeted technology of deep pile foundation construction, Provide reference for construction workers.
