沿海滩涂地区供水管道软基处理方法

Treatment Method of Water Supply Pipeline Soft Ground Foundation in Coastal Beach Area

针对沿海滩涂地区土质松软、土壤含水量大、流动性强、渗透性差、地基承载力低的特点,结合滨州北部沿海地区供水工程输水管线工程实际,介绍了灰土垫层法、换填垫层法、"土工—砂石复合基础"处理法、抛石挤淤法和槽钢钢板桩支护法等滩涂地区软弱管基处理方法,对类似地区软基处理有很好的借鉴作用。

Coastal beach area is characterized by soft soil, high soil water content, strong liquidity, poor permeability and low bearing capacity. Practical conditions of water transfer pipeline in coastal area water supply project in the north of Binzhou are used to introduce lime cushioning method, replacement cushioning method, ＇ geotextile-gravel compound base＇ treatment method, rock rip-rap displacement method, channel steel plate pile supporting method and other weak pipe foundation treatment methods in beach area aiming at the above features, thereby providing reference for soft foundation treatment in similar areas.
