浙江台州高速公路一期工程软土地基综合处理效果的分析――以浙江台州黄岩软土地基 试验路段为例

浙江台州高速公路为主要由淤泥、淤泥质粘土、淤泥质亚粘土组成的软土地基，经过预压法、轻质路堤法、土工合成材料加筋垫层等方法的综合处理，效果明显。在填筑过程中，使路堤保持稳定；在预压阶段，加速了地基的沉降，缩短了预压期；在路堤与桥头衔接部位，减少了两者之间的差异沉降；在高速公路建设的全过程中，增强了路堤的整体性能，提高了软土地基的力学强度，保证了全路段投入运营后的稳定和安全。

ANALYSIS ON COMPREHENSIVE TREATMENT EFFECT OF SOFT GROUND FOUNDATION IN PERIOD 1 TAIZHOU SUPERHIGHWAY PROJECT,ZHEJIANG--A case study for the Tested Part of the Way in Taizhou'Huangyan, Zhejiang Soft Ground Foundation

The soft ground foundation is mainly marine or lacustrine silt and silty caly in Taizhou superhighway, Zhejiang. Through application of the pre-compression method, light-weight embankment method and reinforced earth cushioning with geo-synthetics method etc., the project treatment achieves obvious results. During the embankment construction, the embankment preserves a stabilizing at the pre-compression phase, but the subsidence of ground foundation gets fast and the pre-compression period is shortened. The difference on subsidence is reduced at the linkage between the embankment and the bridge. Consequently, in the whole course of the construction and working of the superhighway, the whole properties of embankment is enhanced and the mechanics strength of the soft ground foundation is strengthened, and the stability and safety is ensured for the future running of the whole superhighway.
