Study On The Effect Of The Bent Structure Of Frame Wharf To The Soil Bank Slope Of Stress Deformation

Due to its adaptability to the condition of inland river waterhead’s change and its effects on the development of the efficiency of handle cargo. Piled port plays an important role in the construction of inland river’s port. The soil bank slope have long-term effects of water level, make slope failure and port damage. This paper mainly based on “The 12 th Five-year” National Science and Technology Supporting Program”Study on the key technology of port and dock construction in channelized reach of mountain rivers”(NO.2012BAB05B04).Based on the model test, this paper studies wharf’s influence on the strain and change of slope. The specific research work and achievements include:(1) According to the similarity theory, the model test design the size of the wharf and slope, determine the layout and loading of the model, and the position of the test point of the strain and change.the model test do the water rate test, density test, screening test, triaxial test and direct shear test. Determined the basic physical parameter of tested soil.(2) Based on the test on sand-shale mixture slope’s model, the model test get the change rule of the vertical change of the test point in the slope under the condition of the load on the slope peak. Besides, the model test analyze the regularities of distribution of side stress with the depth, vertical attach stress coefficient with depth and load distance. Based on water level test, analyze the regularities of stress with water level.(3) Based on the experiment on wharf and slope’s mutual effect, the model test find the change rule of the vertical change of the test point in the slope under the condition of the load on the slope peak. Besides, the model test analyze the regularities of distribution of side stress in the front and rear pile with the depth and study the relationship between side stress and load distance.Based on water level test, analyze the regularities of stress with water level.(4) According to the analysis on the results of all the test above, the paper can draw a conclusion that the existence of wharf have effects on the side stress of test point. It can change the distribution law of side stress with depth and have obvious effect on the distribution law of side stress coefficient. Meanwhile, the existence of wharf decrease vertical change of slope and side stress, reflecting that wharf have the effect of fender, decrease the strain of slope and increase the stability of the slope.Based on water level test, find the slope of stress can change with water level,it can make slope failure and damage.
