锚杆静压桩加固托换技术在工程中的应用

Application of Reinforcement & Underpin Technology in Anchor-bolt Static Pressure Pile

阐述了锚杆静压桩的主要特点、作用机理及设计要点,并通过工程实例,验证了锚杆静压桩在既有建筑物地基基础加固托换及纠倾工程中应用的可靠性。随着工程经验的不断积累,锚杆静压桩将以其独特的施工工艺、可靠直观的加固效果及方便快捷的抢险手段,在既有建筑物加固托换及增层改造工程中,发挥着日益重要的作用。

The paper describes the main characteristics, function, mechanism and design key - points of Such pile, and verifies the reliability of application of such pile in reinforcing and underpinning the foundation of existing buildings and in correcting inclined stuctures. Along with continuous accumulation of engineering experiences and its unique technique, the pile will play an increasingly important function by its secure and direct - view reinforcing effect and convenient and fast measures in dealing with emergency.
