摘要
东莞市掌洲岛沿线堤基存在较厚软土层,其天然承载力和抗剪强度较低,且河水受潮汐影响明显,水位涨落频繁,现状堤基已形成了较为稳定的渗流通道,存在渗透变形、堤基沉降、堤防整体稳定无法满足规范要求等问题。工程选择水泥土搅拌防渗墙截渗和水泥土搅拌桩复合地基处理方案,对现状堤防进行达标安全加固。通过项目的实施,提高了现状堤防的防洪能力,保障了片区人民生命财产安全,有利于促进本地区社会经济持续发展。
The embankment foundation along Zhangzhou Island in Dongguan city has thick soft soil layer with low natural bearing capacity and shear strength,and the river is obviously affected by tide and the water level rises and falls frequently.The current embankment foundation has formed a relatively stable seepage channel.There are problems such as seepage deformation,embankment foundation settlement,and the overall stability of the embankment that cannot meet the requirements of the specification.The cement-soil mixing anti-seepage wall and cement-soil mixing pile composite foundation treatment plan is selected in this project,and the existing embankment is strengthened safely.Through the implementation of the project,the flood control capacity of the current embankment has been improved,and the safety of life and property in the area has been guaranteed,which is conducive to promoting the sustainable development of social and economic of the region.
