Weifang Coastal Disaster Prevention Researc Of Saline Soil Area

Saline soil in China are widely distributed, than the higher salinity of the saline soil, salt expansion, collapsibility, corrosion and other adverse characteristics. The flood area of saline soil embankment is one of the main engineering problems of the rapid development of restricting traffic road construction. This article describes the distribution law of the Weifang area of saline soil and the main categories, as well as saline soil at home and abroad Research. The main contents can be summarized as:the investigation of a saline soil engineering properties;2, analysis of the disease mechanism;3, reinforcement, improvement programs, comparison and selection;4, conclusions and recommendations and innovative point.By analyzing the Weifang City, the coastal saline soil salt distribution law, the raw data of the disposal technologies on the field survey of the coastal areas saline-alkali soil of the roadbed of the highway project is analyzed. Distribution law of the saline soil roadbed under saline soil conditions. Investigation of the roads under different technical conditions, a variety of disease mechanism. Select the Binhai New Area, Binhai Avenue. Hoi Wai Road, Hong Kong Camp Road, Haihe Road and other key projects along the roadbed soil soil sample survey of the saline soil physical and chemical indicators.The subject first summarize the nature of the works of saline soil, the formation mechanism and its hazards, Weifang Binhai Economic and Technological Development Zone, a highway construction for saline soil subgrade salt expansion, melting depression and other major failure modes, from the removal ofsalt, structural reinforcement and water cut off and other measures the effectiveness of prevention and treatment of diseases of the saline soil analysis and comparison of the use of lime, fly ash, cement and curing agents and inorganic binding material single or a combination of improved saline soil engineering properties andthe experimental determination. Finalized through a systematic study on the mechanical properties of reinforcement coastal chloride saline soil and road perfonnance to the carbide slag as a partition layer to eliminate the capillary action of the saline soil, dynamic compaction to increase the discreet nature of the substrate, reasonable drainage set up a modified soil subgrade treatment options.This article draw on saline soil of Projects in this region, research and analysis, and appropriate construction technology, is committed to start a discussion as to solve the problem of disease prevention and treatment of the flood area of saline soil engineering. The novelty of the program is to rely solely on the simple practice of the undisturbed soil mixed lime abandoned to change or avoid the adverse factors that begin in the road area within the maximum substrate, drainage and embankment stability and strength to make the consideration of the co-ordination.
