锚杆静压桩施工技术要求和压桩停滞效应分析

■he constrational technical requiremenis of anchos red static compression piles and analysis of the stagnation effect of compression pile

文中首先介绍了锚杆静压桩施工的程序、要领及质量监控。其次,结合施工场地的土层埋藏条件,分析了压桩的压力P与桩入土深度S间的关系曲线,以及压桩中(终)止的时间效应。最后,介绍了在南京地区,成功地采用锚杆静压桩加固地基的工程实例。

This paper firstly introduces the construction programme, essential points and quality monitoring of the anchor rod static compression pile. Then, in connection with the soil bedding conditions at the construction site, it analyzes the relation curve of the pressure P versus the penetration depth S of the compression pile, as well as the time effect of the stopping of the compression pile. Finally, it introduces the successful case his tory of foundation strengthening with anchor rod static compression piles in Nanjing area.
