摘　　要：依托广州南沙新建滨河路BHLK1+790~+840段深厚软土路基处治工程,进行“长板-短桩”复合地基的现场试验作为一种新的施工方法,并与理论沉降计算进行比较。结果表明:“长板-短桩”地基处理技术将水泥搅拌桩和排水固结法相结合,在对沉降控制较严格的软土地基应用效果良好,为软土地基处理提供了一种新的思路和方法。Based on the deep soft subgrade treatment project of BHLK1+790~+840 section of newly built Binhe Road in Nansha,Guangzhou,the field test of"long plate-short pile"composite foundation treatment is carried out.The test results are analyzed and compared with the theoretical settlement calculation results.The results show that as a new method,"long plate-short pile"foundation treatment technology combines cement mixing pile and drainage consolidation method,which has a good application effect in soft soil foundation with strict settlement control.It provides a new idea and method for soft soil foundation treatment and can provide certain reference for similar projects in the future.
