Abstract.
The results can offer valuable references for both theoretical research and engineering design of long pile bearing larger negative skin friction.
For example, in the construction of the Shanghai international shipping centre Yangshan deep-water port, negative skin friction caused by ultrahigh filling has become a focus of research in the engineering design.

It was indicated that combining the closure gap and overflow was necessary for the closure construction in offshore dyke engineering.
Introduction The most essential component in reclamation project is the closure final which is very important for guaranteeing the safety, schedule and quality of engineering and controlling the engineering cost(Fan Qijin,2004).
If the closure gap width is too wide, it will increase the engineering amount of the closure construction and delay time.

Abstract.
Silt in some areas of our country is very extensive, its distribution is different from the cohesive soil, or sand soil, has unique engineering characteristic.
This article take the G209 (Inner Mongolia Helin to Qingshuihe section) the roadbed silty soil as the study object, study its basic physics, the mechanical properties as well as the distortion and the intensity change rule under the dry-wet circulation, do a comprehensive and systematic analysis about varieties of basic engineering characteristic of the silt in the region Through the condition of dry-wet circulation of unconsolidated tri-axial tests, this article study the silt sample failure pattern under different degree of compaction, stress-strain relations and the change rule of strength.
Therefore, considering the current soil strength and deformation characteristics of the relevant research experience we also use tri-axial test instrument and carry out the dry-wet circulation to silt strength deformation characteristics of the test, so that the research results can more accord with the engineering practice and convenient for the engineering application.

Abstract:the results of deep artificial permafrost 's tri-axial compression test showed that the stress-strain relationship of deep original frozen clay presents a character that is weak and soft From the view point of engineering application , the paper gives a exponential model containing two parameter, Comparative analysis showed that the model not only gives a good description of frozen clay stress-strain relationship before peak stress, but also has the advantages of less model parameters, easy to determine and clear physical meaning.
σ1-σ3=[1-exp(-bε1)] (2) Fig.3 Fit curves of strain stress to frozen clay Because of the engineering practice, artificial freezing soil strength is usually refers to the peak intensity, when strength curve have no obvious peak value, we generally take axial strain for 15% as the frozen soil’s strength value.[4] So from the Angle of the engineering application, type (2) can be used to describe the stress-strain relationship of deep artificial freezing clay tri-axial shear .
(2)From the perspective of engineering application, the stress-strain relationship of the weak soften deep freeze clay can be used with exponential function containing two parameters as to approximately describe, the parameters in the equation can receive from a tri-axial compression test, among them,The parameter is the frozen clay peak intensity,Parameters b reflect the shape of stress and strain curve for frozen clay , the number equal the negative slope value of line:, the R is the ratio of the principal stress and the peak intensity before the peak intensity of frozen clay

Experiment shows that, the method is simple, fast, effective, and accuracy fully meets the engineering measurement needs.
As an important sensor of measuring tilt, inclinometer can be divided into static measurement and dynamic measurement[5],and has the advantages of high resolution, low power consumption, wide measurement range and easy integration etc..Also it has been widely used in the fields of gyro platform, mechanical engineering, civil engineering, aerospace etc..
Above all, we can see that it is a simple, effective, feasible method which fully meets the needs of engineering survey.
So it will have a good application prospect in actual engineering.
