沿海吹填区市政道路基础设施位移控制关键技术浅析

Brief Analysis on Key Technique of Displacement Control of Municipal Road Infrastructure in Coastal Hydraulic Reclamation Area

吹填造陆是利用海积软土或淤泥作为填土资源的一种变废为利的地基处理方式,既可清理海港码头淤泥和疏浚航道,又可缓解沿海地区用地需求急剧增加的矛盾。但吹填造陆需对吹填土进行加固处理,提高其土体抗剪强度和地基承载力,控制市政道路基础设施的位移以满足后续工程建设的要求。以温州市瓯江口新区一期市政工程为背景,浅析吹填区道路位移控制关键技术。

Land reclamation by blowing is a kind of foundation treatment method which uses the marine soft soil or silt as filling resources to change waste into profit,which can not only clean up the silt of harbor wharf and dredge channel,but also alleviate the contradiction of rapid increase of land demand in coastal areas.However,it is necessary to strengthen this soil to improve its shear strength of soil body and bearing capacity of foundation.The displacement of municipal infrastructure is controlled to meet the requirements of subsequent engineering construction.Taking Wenzhou Oujiangkou New District Phase I Municipal Project as the background,the key displacement control technique of roads in the hydraulic reclamation area is briefly analyzed.
