Because of high compressibility and low strength of soft soil, especially fluidal plastic silt soil, which has a engineering properties of “Three low Three high” - high compactness, high water content, high porosity, low strength, low compression modulus, low permeability, consolidation settlement under the loads could easily occur.
Combined with site soil characteristics, comprehensive considering the time limit, engineering cost, processing requirements and other factors, by comparing all types of soft soil foundation treatment methods, the dynamic drainage consolidation method is chosen for this treatment of foundation.
The highway engineering soft foundation treatment.

Mechanical Properties of Flexible Structureswith Helical Reinforcements under Axial Load Wei Huang1, a, Jian Shan1, b, Zhenjiang Weng1, c 1Department of Civil Engineering, Southeast University, 2 Sipailou, Nanjing, Jiangsu,China ahuangwei_jeff@163.com, bshanjian@hotmail.com, czhenjiang001@163.com Keywords: mechanical property;flexible structures; helical reinforcements; geometric nonlinearity; contact pressure Abstract.
Flexible structures with helical reinforcements are widely used in engineering because of their low bending stiffness and highstrength.To strengthen the core, we focus on those structures which the helixes will contact the inner core loaded axial tension.Thecontact pressure between layers is taken into consideration and eliminated by using deformation compatibility equation.
Introduction Combining low bending stiffness with high tensional and torsional stiffness, flexible structures with helical reinforcement are widely used in engineering.
