注浆混凝土桩在杭千高速公路路基处理中的应用

<title>e Application of the Grouting Concrete Pile to the Ground Improvement of Hangzhou Freeway

注浆混凝土桩是预填骨料压浆混凝土桩,它是近几年新开发的一种桩型。本文通过注浆混凝土桩在杭千高速软弱地基中的应用,具体讨论了该桩的设计理论和施工工艺,着重分析了设计施工中的关键-砂浆配比问题,并初步探讨了注浆混凝土桩施工过程中易发问题及其处理措施,以期为这种桩的推广应用提供借鉴作用。

<abstract>e grouting concrete pile is a new type of concrete pile filled coarse rubble which has just been developed in recent years. On the basis of the application of the grouting concrete pile to the ground improvement of Hangzhou freeway, the design theory and construction technique specifically has been put forward. The key, the ratio of cement mortar,in the design and construction has been analyzed emphatically and detailedly. And also the problems which are easy to occur in the construction and the measures of solutions have been discussed. The conclusion provides reference for the application and generalization of this pile.
