“长板-短桩”在软土路基处理中的应用

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。

Application of Long Plate-short Pile in Soft Soil Subgrade Treatment

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.
