置换碎石桩联合强夯在北部湾填海复杂型软弱地基处理中的应用

Application of Replacement Detritus Pile with Dynamic Compaction in Treatment of Complex Sea-filling Soft Ground in Beibu Gulf

从广西北部湾大量填海(塘)造陆工业基地所遇到的复杂型软弱与夹层地基处理工程实例中,结合建(构)筑物具体特点,扩展应用置换(挤密加固,纵横排水)碎石桩联合强夯的地基处理方法,在解决大面积地基不均匀沉降,软弱夹层纵横排水与挤密固结、综合夯实提高总体地基持力层承载力方面取得了"安全、经济、高效"的良好效果,并具有推广前景和意义。

With the engineering case of ground treatment for complex soft interlayer of industrial base in land accretion of Beibu Gulf of Guangxi, and according to the specific characteristics of building structures, replacement detritus pile with dynamic compaction method was further applied with good effects in overcoming the large scale of differential settlement of the ground, crossbar drainage, compacting consolidation and improving the bearing capacity of bearing layer.
