人工海岛建设技术现状与同步建造新思路
Review of artificial island construction technology and innovative approaches to synchronous construction
摘要
Abstract
With the continuous growth of urban development,ocean resource exploitation and tourism demands,the construction of artificial islands has become increasingly important.Traditional methods for constructiing artificial islands mainly include non-cofferdam reclamation and cofferdam-based wet reclamation.However,these methods have several problems:the ground treatment lacks systematic reinforcement measures,which can easily lead to significant settlement;the construction process of backfill materials is prone to disturbing the marine environment,affecting water quality and the ecosystem;and there are repetitive excavation procedures in subsequent engineering construction,increasing the workload and costs.To address these issues,a synchronous construction method,namely dry reclamation with cofferdam,is proposed for building artificial-island cities.The specific procedures of this method are as follows:cofferdams are constructed facing each other on the outer sides of the designated area,while offshore cement-soil mixing piles are used to reinforce the ground in the filling area;after the cofferdam is completed,seawater is pumped out and a cushion layer is evenly laid on the original seabed;building pile foundation are then constructed,followed by the installation of prefabricated underground structures such as tunnels,pipe galleries,and basements at the bottom elevation.Simultaneously,soil backfilling is carried out layer by layer.This process is repeated structural construction and soil backfilling until the backfill reaches the specified elevation.The synchronous construction method can reduce the amount of filling material and the cost of re-excavation,which can greatly shorten the construction period and lower overall costs,and reduce environmental pollution during the reclamation process.The research results can provide a new option and reference for construction of large-scale artificial islands.关键词
