摘要
秦沈客运专线东段优质填料严重缺乏 ,对沿线大量的粉砂土必须进行稳定改良而加以利用。通过对粉砂土掺和角砾土机械稳定改良的试验研究 ,寻求改良土混合料经济合理的配合比和切实可行的施工工艺 ,以满足高标准铁路路堤填料的要求。从而达到在现有的料源及施工条件下既能满足高标准铁路路堤填筑质量要求 ,又能降低工程造价的目的。
In order to solve the problem that the high grade filling material is seriously lacking on the east section of Qinhuangdao Shenyang Passenger Transport Special Railway, the silt in large amounts along the railway must be improved, so that the silt can be used. In this paper,the silt is improved through mixing with gravel and being stabilized mechanically.The aim of the test for the improvement of silt is to find out the economical and reasonable ratio of matching and the practical technology of construction on the mixture of improved soil, so that the requirement of high standard railway embankment in filling materials can be fulfilled.Thus under the existing conditions of materials source and construction technology,not only can the construction quality of high standard railway embankment be guaranteed,but also the cost of the project can be cut down.
