[Abstract]:Suction dredger occupies a large proportion in dredging engineering vessels. The construction process of strangulation excavation is extremely complex, which is greatly influenced by meteorological, hydrological and geological factors, so it is difficult to formulate accurate and reasonable construction schedule. In this paper, a computer simulation method is used to simulate and analyze the dredging construction process of a stranded dredger. The main research work and research results are as follows: (1) systematically analyzing the construction characteristics of the suction dredger, identifying and quantifying the engineering risk in the construction process of the dredger, and determining quantitatively the construction productivity of the suction dredger. And by using the hierarchical modeling method, the simulation model of the construction of the stranded dredger is established, which can describe the construction process of the suction dredger in a more comprehensive way. By coupling the whole face of the construction at any time with the relevant construction information, the model can be used to describe the construction process of the dredger. The dynamic simulation analysis of the excavation construction process of the suction dredger is realized, the logical relationship of each construction procedure in time and space is reappeared, and the complex process of excavation construction of the suction dredger is expressed comprehensively. The simulation results of the whole process of dredger excavation construction are intuitively analyzed and verified effectively. Aiming at the characteristics of dredger excavation construction, the system simulation and circular network technology are adopted. A digital simulation program for the construction of stranded dredger is developed and applied to the dredging project of foundation slot and harbor pool of actual wharf, which provides a powerful calculation and analysis tool for the design of excavating construction scheme of the dredger.
