组合桩基础在改扩建工程中的应用

Application Reseach of Composite Foundation Piles in Renovation Engineering

改扩建工程桩基础施工直接影响既有建筑安全。通过对静力压桩挤土效应的计算,在改扩建工程基础施工中选择合理的桩型组合,可解决设计施工难题,降低工程造价;工程实例也验证了预期,为类似工程提供借鉴。

Because foundation piles construction can affect the security of the current building in renovation engineering,by means of calculation the soil-displacement effects of soil-displaced piles,composite foundation piles construction can settle the problem of design and construction and save construction cost by selecting the suitable piles style.The practical example has proved the artiapation to be feasible,which has provided the reference for the similar engineering projects.
