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.

The roadway rock has some engineering features of soft rock.
Through launching sound wave to medium with manual shaken method, and receiving the modulated sound wave, at a distance, including its physical characteristic as propagation velocity, amplitude, frequency and so on, it can solve some relevant problems in geotechnical engineering after data processing and analysis.
The instrument can be used to detect surrounding rock loose, range of fracture, and provide scientific basis for design and construction of tunnel design and construction, this Instrument as mine intrinsically safe and can be used for gas mine, metal mine, tunnel and underground engineering surrounding rock qualitative evaluation.
In this type, rock show that the engineering characteristic of soft rock, the surrounding rock loose circle hulking deformation is large, the early convergence deformation speed of surrounding rock is high , the deformation duration is long, and mine pressure appear bigger, so it is difficult to support.
