一、工程概况沪宜线宜兴至漕桥段改建工程是在原有二级公路的西侧拓宽成为二块板式的24m宽的一级水泥路.其中,拓宽部分设计要求做60cm厚6%剂量石灰土的底层和27cm厚12%剂量石灰土的基层.沪宜线宜漕段石灰土施工路段地处苏南水网地区,全线均属软弱地基,而且阴雨雪天约占总天数的1/3.另外,从工程和工期方面来分析尚有三个特点:(1)由于在石灰土施工前一般路段土方已填足,因此,只能采用半幅施工的施工方法;(2)石灰土工程量大,总工程量达33.1万m~3,石灰总用量达4.1万t;
First, the project overview Shanghai Yixing to Caoqiao section of the reconstruction project is to expand the west of the existing two roads to become a two-plate 24m wide first-class concrete road which widening part of the design requirements of 60cm thick 6% dose of lime The base of soil and the base of 27cm thick 12% limestone soil. The limestone construction section of Yichang-Shanghai section is located in the southern Jiangsu water network area, all of which are weak foundations, and rainy and snowy days account for about 1/3 of the total days. In addition, there are three characteristics of engineering and construction period analysis: (1) Due to the fact that the earthwork has been filled in the common road before limestone construction, only half construction method can be adopted; (2) , The total amount of 331000 m ~ 3, the total amount of lime up to 41000 t;
