Dynamic Analysis And Application Of Soil Allocation Balance In Dredging And Filling Engineering

Due to the complex soil condition,complex construction environment and a large number of construction processes,the soil allocation process of dredging and filling engineering is easily affected and restricted by the external natural conditions.Meanwhile,most of the dredging and filling soil materials are in the underwater environment.The soil conditions are not only difficult to identify,but also have great dynamic changes and anisotropy.Therefore,it is very difficult to formulate a scientific and effective soil allocation plan of dredging and filling engineering.Aiming at the key technical problems of the dynamic soil allocation and focusing on the process of soil dynamic allocation in dredging and filling engineering,three-dimensional soil modeling in complex environment,based on the three-dimensional soil model dredging soil excavation analysis and etc.,this paper carried out in-depth systematic study.The main research achievements can be embodied as follows:(1)Based on the detailed analysis of the construction technology of dredging and filling engineering,the mathematic model of the soil allocation in dredging and filling engineering is established.The mathematic model truly reflects the construction process of soil allocation and provides the model basis for optimization analysis of the soil dynamic allocation in dredging and filling engineering.(2)Aiming at the complexity and particularity of the construction object of the dredging and filling engineering,taking into account the diversity of sources of soil information,the anisotropy and the uncertainty of the soil distribution,using three-dimensional Multi-accuracy dredging soil modeling method achieves a complex three-dimensional modeling of underwater soil conditions and ensure the accuracy of the three-dimensional soil model.(3)According to the characteristics and actual demand of dredging and filling engineering construction and based on the above three dimensional soil model,the paper puts forward the calculation and analysis method of soil excavation quantity of dredging and filling engineering and realizes the soil excavation quantity analysis of dredging and filling soil material.(4)Combined with the actual engineering,based on the above theoretical methods and techniques,the calculation and analysis system of dynamic soil allocation in dredging and filling engineering is developed by using computer technology.The system realizes the balanced analysis of the process of the soil allocation and determines the reasonable soil allocation scheme.It provides effective technology platform for the work of design and construction in dredging and filling engineering.
