The slug test is a field-testing method to evaluate the hydrogeological parameters by recording the instantaneous change of the underground water level.Basing on abroad development of slug test,this paper tried to measure some parameters of aquifer with middle and high permeability using high accuracy testing.According to field tests and existing pumping data,the paper firstly discuss every theoretic model,and its difference.Secondly,it analyze and compute the hydrogeological parameters of a certain spot in Chang Chun by classical Cooper Model.At last,comparing with pumping test,the accuracy of the test,which provide scientific basis for its application and generalization,is verified.

The marine soft soils often existed in the foundation of port engineering,which are the saturated soft clay with high rheological properties and the secondary consolidation deformation is of a certain proportion in the total deformation.The coefficient of secondary consolidation is an important parameter used to calculate the amount of secondary consolidation deformation.The conventional methods for computing the secondary consolidation deformation of soft soils do not reflect the influence of loads.However,large numbers of tests show that the secondary consolidation is obviously influenced by loads.Taking the Sanya marine soft soil as the example,the relationship between the characteristics of the secondary consolidation deformation and the loads are analyzed based on laboratory testing data.Some significant conclusions are obtained so as to guide the design and engineering practice of marine soft soil foundations.

There is a large area of soft soil in distribution in Yingkou—Liaobin Economic Area.The authors divided the studied area into the grade Ⅰ—engineering suitability good area,grade Ⅱ—engineering suitability general area and grade Ⅲ—engineering suitability less area,according to the bearing capacity calculation of soft soil layer and settlement calculation of normative method for shallow foundation,with 55 mm as the boundary of foundation's additional settlement and combining with indexes of engineering risk.The grade Ⅰ zone mainly distributes in the west of Yingkou City and the south of salt region,grade Ⅱ mainly distributes in southwestern Yingkou City and the areas except the south of Liaobinxiang and salt areas and the grade Ⅲ mainly distributes in eastern Yingkou City.The areas of the grates Ⅰ,Ⅱ,Ⅲ are accounted 10.6%,86.2% and 3.2% of total area of soft soil in this Economic Area,respectively.
