Research on Highway Pre-Compression Term on Alluvial Flat Soft Clay Treated with Packed Drain Well

Abstract:

The joint road of Jiaozuo-Gongyi Yellow River bridge in Henan province is built on the Yiluo River alluvial flat soft ground. The total length treated with packed drain well is 1384 meters. To guarantee project quality and summarize the deformation rules of the alluvial flat soft clay, 15 representative sections are selected and 38 settlement plats are set. The observation has been lasting more than two years from construction to precompression term. By analyzing the characteristic of the soft clay, the settlement type of precompression, the settlement standard of post-construction and the settlement rate of precompression, that the precompression term is not needed is put forward on the alluvial flat soft ground treated with packed drain well.
