Highway Construction Of Soft Soil Foundation Treatment Technology Analysis And Application

With the rapid development of our country,the high grade road construction demand is also constantly expanding.But because of the particularity of the geological formation of the road,there are often deep soft soil layers along the roadbed.When the road is built on the soft soil foundation,if improper handling of the foundation,may be due to foundation settlement or differential settlement is too large affect the normal use of the road.The processing of soft soil foundation quality directly affect the subgrade bearing capacity of the foundation,but also the key to ensure the safety and efficient operation of the road.So the reasonable selection method of soft ground and rapid implementation,as to achieve the desired economic and social benefits.This paper introduces the definition and characters of soft soil,the cause and harmfulness of soft soil,common soft ground treatment methods and the comparison of various processing methods.The theory as the research foundation,contact with soft soil foundation consolidation principle and the soil rheological characteristics and the phenomenon of common law of subgrade settlement,deeply discusses the research and the scope of application of the common soft soil foundation improvement method in today's society.The seven road Handan City Industrial Park as an example for the weft,in view of the silt engineering planting soil,geological and geomorphological features of the abandoned pit,using a variety of treatment methods of soft soil foundation improvement technology,to do the specific analysis of processing techniques and the construction method used in this project.Finally,the settlement of soft soil foundation is analyzed by the settlement monitoring.,it shows that in this project for soft soil foundation,using jackstone,geogrid and soil with the way of joint construction to be successful,and the soft soil foundation after treatment can meet the requirements of the design code.At the same time,it also made clear the shortcomings of this paper and the direction of further research in the future.
