【摘要】 琼州海峡铁路轮渡北港防波堤在爆破挤淤施工中,出现了堤心石未能落到设计深度的异常情况。通过对防波堤下卧软土层的试验研究,发现问题的根源在于忽视了软土的结构性,在此基础上对下卧软土层进行了沉降及稳定性验算,结果表明它能满足作为持力层的要求,从而为防波堤的评价提供了依据。更多还原

【Abstract】 In the underwater explosion,silt discharge,backfilling stones of Qingzhou Strait breakwater construction, the backfilling stones can’t reach the designed depth.In this paper the properties of underlying soft soil are presented and it is found that the problem resulted from the effect of its structured strength.After that,the settlement and stablitiy of breakwater are evaluated and it is proved that the underlying soft soil fits to the requirement of bearing capacity.更多还原
