摘　　要：根据厦门岛西岸线整治工程B标段173m长岸线采用水下真空联合堆载预压处理软土地基的工程实例,介绍真空联合堆载预压在潮间带软基处理工程中的设计、施工、监测及加固效果。通过成功地应用水下真空联合堆载预压技术,并与同等的堆载预压加固方法进行比较,认为该方法具有施工工期短、软基强度增长快、地基沉降量小且造价低的优点,可供类似工程参考。Underwater vacuum ＆ loading, precompression（UV ＆ LP） technique for treatment of soft soil along 173 m west shoreline of Section B at Xiamen Island is introduced.The design, construction, monitoring and reinforcing effect of UV ＆ LP for soft foundation treatment at tidal zone are presented. Its successful application and comparison between this method and other loading precompresson methods have revealed that this method possesses the characteristics of short construction period,quick increase of strength of soft foundation, small foundation settlement and low cost, and thus may serve as a reference for similar projects.
