摘要
结合工程实例,从技术可行性和经济可行性两方面探讨高层建筑桩基础的选择,介绍泵吸反循环钻孔扩底灌注桩的应用特点及钻孔扩底灌注桩施工过程中的关键技术,并展望了钻孔扩底灌注桩的应用前景。
Based on the engineering example, discussion is given to the foundation selection of high-rise building in terms of technical and economical feasibilites, and introduction is made to the application charac-teristic of pump-absorption anti-cycle drilling bottom-enlarged grouting piles and its key construction techniques. At last, application prospects of the piles are predicted.
