厦门怡山商业中心逆作板墙深井灌注桩成套施工技术 张明，王光禄，苏伟 （中国建筑第四工程局有限公司厦门分公司，福建厦门361000） [摘要】厦门怡山商业中心塔楼共设大直径逆作板墙承压灌注桩24根，桩身直径2.4~3.2m，桩长50-60m，扩大 头直径6.8m，单桩承载力32000~51000kN。

结合工程地质条件，介绍了地下连续墙止水、逆作板墙施工、深井灌 注桩施工、安全综合技术及后注浆技术等关键技术。

以目前的试验设备及现场施工条件，无法进行本项目超大荷 载静载试验，故在逆作板墙深井扩底灌注桩底-55m处用桩底平板荷载试验代替静载试验验证桩底持力层参数。

实践证明，逆作板墙深井灌注桩成套施工技术应用效果良好。
