摘　　要：本文通过南市区西陵高层打桩施工的实例,分析了各种打桩防护措施的作用和效果。认为打桩对周围环境产生的公害是一个动态过程。因而,根据场地的工程地质条件和打桩的进程,配以适当的防护工作量,并根据打桩过程中场地孔隙水压力和地基土变形的规律及时调整打桩流水的情报化施工方法,降低了防护费用,并可大大减少对周围环境的影响。This paper presents an analysis of the functions and effects of various protective measures for piling through the example of the piling and construction of Xi-ling high-rise in Nanshi District. The public calamity made by piling to the surrounding environment is a dynamic process. Based on the engineering geological conditions of the site and the piling process with suitable amount of protective work, and on the pore water pressure of the site during piling and the regularity of deformation of the foundation soil, the feed-back construction method of the in-time rearrangement of the piling process reduces the protection expenses and its effect on the surrounding environment.
