摘　　要：对温州地区桥梁基础钻孔灌注桩进行了后压浆试验研究,结果表明其承载力比常规钻孔桩的承载力提高37.5%以上,同时提出了桥梁后压浆钻孔灌注桩设计计算方法、施工工艺,证明在温州地区高速公路工程中的应用是成功的。The experimental study on the cast-in-situ drilled piles with grouting is performed on the bridge foundation in Wenzhou. As a result, the bearing capacity can be increased more than 37.5 % compared with the normal one. The calculating method and the construction technology of the cast-in-situ drilled piles with grouting are elaborated. Compared with the static loading experiments, the application of the cast-in-situ drilled piles with grouting is testified to be successful in the highway engineering of Wenzhou.
