静压注浆法在既有构筑物地基加固中的应用

Application of Static Pressure Grouting Method in Foundation Reinforcement of the Existing Buildings

摘要:

通过对中石油天津分公司塘沽油库4#储油罐工程沉降超限原因的分析，找出了引起桩基础沉降的主要原因，从而采用静压注浆的地基处理方法，有效地改善桩间土的水理性质，提高了桩间土摩擦阻力，地基的加固缓解和消除了既有构筑物的沉降问题。

Abstract:

Through analysis on No.4 tank project overrun subsidence of Tianjin Branch Company attached to China Oil Limited Corporation, main reasons caused the subsidence of piles foundation are found. By using static pressure grouting treatment method, water physical property between piles has been improved, the friction between piles have been increased. Foundation reinforcement can relieve and eliminate the subsidence problems occurred in existing buildings.
