Diversion tunnel stress redistribution and inner water pressure influence scope;

In order to study the influence scope of vacuum preloading,Plane Strain Finite Element Method is employed to analyze the effective influence depth and horizontal influence scope of soft ground improvement by vacuum preloading in combination with the experimental results in the Jialichen Bridge site.

In defining local exclusive legislative authority,we should adopt comprehensively the standards of "influence scope" and "importance" of affairs,and begin with defining "local affair.

Cloud model of deciding study area in traffic impact analysis;

However,different realizing methods for the same change requirements may result in very big different impact ranges.

The four factors were discussed,including the intensity of land use in the determination of impact range,the conditions of surrounding road network,the accessibility of public transportation facilities and the project its.
