摘要
介绍了在湛江滨海围海造陆工程中,以吹填砂为堆载,采用塑料排水带对深厚淤泥进行处理的工程实例。该工程的特点是在严密的监测下,吹填进度和加荷速度一并考虑,围海造陆过程与软基处理过程融为一体。这不但节约了投资,也缩短了工期。长期沉降观测结果表明,该法使约13m厚的淤泥在最初的2a时间内实际固结度达到80%以上,从而大大地加快了淤泥的排水固结速度、缩短了固结期。
An engineering example is introduced,which applies prefabricated strip to treat the deep silt with dredger-reclaimed sand as load in Zhanjiang reclamation project. With careful monitoring, considering the accordance of the construction schedule and the loading speed, the reclaiming process is integrated with the treatment of soft soil in this case. The investment is therefore decreased and the term of works is shorten. The result of the long-term settlement observation shows that the degree of consolidation of the 13-meter-thick silt is above 80% at the end of the first two years, which indicates that the method can increase the consolidation speed.
