地下综合管廊软弱地基处理技术的优化及应用

Optimization and application of soft ground treatment technology of underground comprehensive pipe gallery

针对沿海地区地下综合管廊在自身结构体积大、自重大等内部因素和地下水(侧向压力、地下浮力)、土层性质和埋深等外部因素影响下,根据不同的影响因素组成采取不同的经济有效的地基处理方式,并在原有的施工工艺上进行优化调整,从而达到了良好的地基施工质量控制效果。

Aiming at the internal factors such as large volume,heavy weighted and the external factors such as groundwater （lateral pres- sure, underground buoyancy） , soil properties and depth on underground pipe rack for coastal areas, according to the different factors, different economic and effective foundation treatment methods were adopted and optimization adjustments on the original construction technology were carried out. Construction quality was controlled perfect so as to achieve the good foundation.
