深厚软基傍河拓宽路堤稳定分析及技术实践

Stability Analysis of Embankment Nearby Brook on Deeply Soft Soil Foundation and Treatment Practice

在深厚软土地基条件下,提出了一种新的傍河路堤拓宽技术,该技术利用轻质泡沫混凝土现浇的流动性、硬化后的自立性以及强度可调等特性,巧妙结合工程实例实现了不占河、不改路、不征地条件下傍河老路堤的非机动车道拓建,而且有效保护了路侧行道树和沿河景观,技术实施便利、快捷、质量可控。实践表明,该技术方案对类似工程条件具有示范效应,值得借鉴。

This paper proposes a new way to construct embankment extension project nearby brook on deep soft soil foundation. It takes the technology of lightweight foamed concrete cast-in-situs properties as liquidity, independence or adjustable compressive strength after hardening. In old embankment extension example, it cleverly combines with series of objects as without changing the river or road course, without charged land to handle along the riverside to achieve non-motor vehicle lanes extension,and effectively protects the roadside trees and landscape along the river. The new technique is implemented conveniently, fast and with satisfied quality control. Practice shows that the technical solution has a demonstration effect on similar engineering conditions. It will be used for reference.
