Structure Characteristics Research On Inland Overhead Vertical Wharf With Inclined Rock-socketed Piles

After the three Gorges dam was completed and put into operation, all terminals inthe reservoir area of fluctuating backwater area are at long last, greater water depth andalong with the steep rise and steep fall of water level in flood season in the complexhydrological conditions of the problem. Existing river aerial vertical Terminal structure,have too many vertical and horizontal links make some negative effects to rivernavigation such as flood. Both caused sharp increase in construction jobs on the waterwhen the project, while allowing construction costs significantly. Traditional overheadvertical wharf structure calculation analysis get similar inch beach first and secondphase of the structure stiffness is bigger surplus, So, how to make wharf structure tomeet the complex hydrogeological conditions, after the three gorges reservoir. Makesthe wharf structure in many terminal load effects at the same time ensure the safety ofwharf structure of normal use. How to solve the existing wharf infrastructure in verticaland horizontal contact support too much, cause structural block water area is too large,water quantity and the cost of a substantial increase. To solve above problems in thispaper do some research as follows:(1) Through the construction water level of inland traditional vertical wharfstructure determined methods of the research, combine the duration curve river reservoirwater level after the three gorges reservoir, Discuss the inland overhead vertical wharfconstruction water level of the construction of the determination after the three gorgesreservoir, and determine the rational construction water level.(2) Existing inland overhead vertical wharf structure in use more and more contactto stay in as well as increase the structure stiffness structure increases friction of waterarea, water homework quantity greatly increased, and the large increase in the projectcost. That is to say, the existing inland wharf structure can no longer be good satisfy thewharf construction on structure in navigable flood discharge, construction period,economic and other aspects of the requirements. Through research, the feasibility ofnew type wharf structure construction. In this paper,"Take inclined rock-socketed pileof inland river overhead vertical wharf structure" is used to solve these problems.(3) In this paper, the second phase in the Chongqing port orchard areas as anexample. According to the proposed "take inclined rock-socketed pile of inland riveroverhead vertical wharf structure" using the large-scale general finite element calculation software ANSYS and the C#programming language, by programming theoverhead vertical wharf structure mechanics response under single load value arecombined, got by calculation of quay structure section within the working condition ofhorizontal and vertical components of the most unfavorable load combination valuesand their combination type and Guoyuan second phase compare calculation results. Andthe structure modal analysis, the structure dynamic characteristics.(4) By "take inclined rock-socketed pile of inland overhead vertical wharfstructure" construction feasibility study, The determination of reasonable constructionwater level and structural type selection and makes the structure of the existingconstruction difficulty of the straight pile multilayer freely contact support structure hassignificantly reduced, Construction cost is reduced, And through its characteristicresearch shows that this structure can satisfy the normal use of wharf structure is a kindof feasible wharf structure.
