摘要
将空箱挡墙技术应用在云梦大闸的改建工程中.首先,根据闸址区工程地质情况,提出了地基加固处理措施.在工程设计部分,给出了空箱挡墙平面图、纵剖面图、地下轮廓线及典型段的分简图.然后对空箱挡墙的稳定性进行了分析验算,主要包括水闸渗透稳定计算和挡墙抗滑稳定及基底应力计算.结果显示,在基本荷载组合和特殊荷载组合两种工况下,空箱基底应力的不均匀系数和抗滑稳定安全系数均满足设计规范的要求.将空箱挡土墙技术应用在云梦大闸的改建中,可以增加水闸的整体稳定性.
The hollowed retaining wall technology was applied in project of Yunmeng main gate.First,the mea-sures for strengthening the foundation were proposed according to the engineering geological conditions of thesite.The diagram of plan,longitudinal section and the underground contour and typical segment diagram of hol-lowed retaining wall were given respectively for the engineering design.Then,the stability of hollowed retainingwall was analyzed,including seepage stability calculation of sluice gate and anti-sliding stability of retainingwall.It demonstrates that the uneven coefficient of stress of empty base and anti-slide safety coefficient can meetthe design requiremen under two kinds of conditions,the basic load combination and the special load combina-tion.We suggest that we should adpot the hollowed retaining wall technology to improve the overall stability ofthe sluice in Yunmeng main gate.
