武汉国际会展中心深基坑工程设计与施工

Design and Construction of The Deep Foundation Ditch Project of Wuhan International Meeting and Exhibition Center

武汉国际会展中心深基坑工程开挖范围广、深度深、施工难度大 ,支护结构采用“连锁灌注桩加预应力锚杆”、“钻孔灌注桩加预应力锚杆”、“喷锚网”和“土钉墙”等多种方式 ,降水采用止水帷幕加中深井降水的形式。经过一年多的各项监测表明 ,基坑边坡及周围建筑物稳定 ,保证了基坑工程顺利施工。

The construction of the deep foundation ditch project of Wuhan International Meeting and Exhibition Center was very difficult. Its support structure adopted many methods such as linkage grouting pile and pre stressed anchor, drilling grouting pile and pre stressed anchor, sparging and anchoring net and soil nail wall and so on. Its water\|lowering methods used water seal curtain and mid deep well water lowering. The monitoring more than one year indicates that side slopes of the deep foundation ditch and surrounding buildings are stable and these methods also ensure the successful construction of the deep foundation project.
