1 引言 淮河入海水道1999年度阜宁Ⅱ标段境内,在0～-1.5m位置上有一层1.5m厚呈灰色淤泥质粉质粘土,强度低,标准贯入击数1～2,含水量高,天然含水量48％～52％。该类土近100×10~4m~3,占整个标段工程量的20％,严重制约着工程进度和工程质量。采取何种施工工艺,使其压实度达到设计的要求,有助于用这类土筑堤,我们按照碾压试验的要求进行了有益的探讨。
1 Introduction Huaihe River into the sea 1999 annual Funing Ⅱ tenders in the 0-1.5m position there is a layer of 1.5m thick gray silty silty clay with low intensity, the standard penetration rate of 1 to 2, high water content , Natural water content of 48% to 52%. This kind of soil is nearly 100 × 10 ~ 4m ~ 3, accounting for 20% of the total tenders, seriously restricting the progress of the project and the quality of the project. What kind of construction technology should be adopted to make the degree of compaction meet the design requirements and help to embankment with this kind of earth, we conducted a useful discussion in accordance with the requirements of rolling test.
