摘　　要：结合应用预应力混凝土管桩处理高速公路软基础的工程实践,针对预应力混凝土管桩打桩施工中产生的振动影响问题,采用了仪器监测和理论分析相结合的研究方法,监测方案为在个别建筑物进行实时监测并采用线性布点,理论分析采用基于萨式公式的数学模型并应用最小二乘法进行回归分析,最终得到了本次打桩施工对附近建筑物的影响范围,同时也为解决相关工程问题提供了借鉴和参考。Based on the engineering practice of using pre-stressed concrete piles to treat soft foundations of highway,the vibration effect caused by pre-stressed concrete pile piling construction is discussed and the method of combining instrument monitoring with theoretical analysis is adopted.The monitoring scheme is to carry out real-time monitoring in individual buildings and to adopt linear layout.The theoretical analysis relies on mathematical models based on the Sarbanes formula and applies least squares regression to obtain the impact area of the piling on nearby buildings.The present study provides reference for solving relevant engineering problems.
