摘　　要：针对常规真空预压排水固结法施工时间长、工后沉降大等缺点,提出太阳能加热排水固结法。对系统组成、软土地基处治工艺进行详细叙述,并对经济性、碳排放量等进行分析。研究结果表明,与常规真空预压法相比,太阳能加热排水固结法处理地基固结速度较快,可增加约11%的固结度,提高约11%的地基强度,缩短约32%的工期,减少近18.4%的碳排放量,当施工时间成本>2165元/d时可降低地基处理的整体成本。Aiming at the shortcomings of conventional vacuum preloaded drainage consolidation method,such as long construction time and large post-construction settlement,this paper proposes a solar energy heating and drainage consolidation method.The system composition and soft soil foundation treatment process are described in detail,and the economy and carbon emissions are analyzed.The research results show that,compared with the conventional vacuum preloading method,the foundation consolidation speed of the solar energy heating and drainage consolidation method is faster.It can increase the degree of consolidation by about 11%,improve the foundation strength by about 11%,shorten the construction period by about 32%,reduce carbon emissions by nearly 18.4%.When the construction time cost is more than 2,165 RMB/d,the overall cost of foundation treatment can be reduced.
