| 摘 要： | 针对横琴地区最大深度逾40 m的深厚软基，根据低填土路堤的特点，结合工程地质、岩土层特点，对路基的填土高度、软基处理深度、验收标准进行分析，分别对一般路段、既有路基衔接路段、结构物衔接路段、净空受限路段等，提出真空联合堆载预压、双向水泥搅拌桩、长短桩复合地基和高压旋喷桩综合处理方案。工程验证，软基处理效果明显。

Soft Subgrade Treatment Design of Low Embankment in Deep Soft Soil Area |
| |
| Abstract: | This paper introduces the deep soft foundation with the largest depth of more than 40 m in Hengqin area. According to the characteristics of low embankment, combined with the engineering geological characteristics of rock and soil, the subgrade filling height, soft foundation treatment depth and acceptance criteria were analyzed; For the general section, both cohesion and structure cohesion road subgrade sections, clearance of limited road, the treatment schemes of vacuum preloading, the bidirectional cement mixing pile, the long-short pile composite foundation and high pressure jet grouting pile were proposed. It provides reference for the design and construction of similar soft foundation treatment projects. |
