Embodiment 1

[0029] This embodiment is aimed at the method for forecasting sediment deposition of the trenchless harbor basin channel, including the following steps:

[0030] The first step is to collect the environmental parameters of the target non-excavation harbor basin channel. The environmental parameters include the sediment content S of the water body and the median particle size of the sediment d 50 , The average water velocity V before the construction of the harbor basin channel 1 , After the construction of the harbor basin channel, the average water velocity V 2 .

[0031] The unit of water body sediment content S is kilogram / cubic meter, and the median particle size of sediment is d 50 The unit is mm, and the average velocity of the water body V before the construction of the harbor basin channel 1 and the average water velocity V after the construction of the harbor basin channel 2 The units are the same.

[0032] Among them, the sediment content of the water body S, th...

Abstract

The invention relates to a sediment accumulation forecasting method aiming at a trenchless harbor basin channel. The sediment accumulation forecasting method aiming at the trenchless harbor basin channel comprises the steps of collecting environmental parameters of the targeted trenchless harbor basin channel, wherein the environmental parameters comprise the sediment concentration S of the water body, the sediment median diameter d 50, the average flow rate V1 of the water body before the construction of the harbor basin channel, and the average flow rate V2 of the water body after the construction of the harbor basin channel; calculating the dry density gamma 0 of the sedimentation body and the sedimentation settling velocity omega according to the sediment median diameter d 50; calculating the sedimentation volume PB which is the forecasting result within a predetermined sedimentation time t. The method is capable of better forecasting sediment accumulation of the trenchless harbor basin channel, reasonable and reliable in forecasting result, and playing a role in guiding port site selection, channel route selection and port and channel continuous running cost calculation.

Description

technical field [0001] The invention relates to a method for predicting sediment deposition, in particular to a method for predicting sediment deposition for a non-excavation harbor basin channel, belonging to the field of port channel sediment engineering. Background technique [0002] As far as the applicant knows, my country's port construction and development has been at its peak in the past ten years, and the problem of port channel sediment is a key issue related to the selection of port sites, channel selection and the continuous operation cost of port channels. Sediment engineering research presents new challenges. [0003] Forecasting the degree of sedimentation can measure the severity of sedimentation, but the current forecasting methods are all for the excavated harbor basin channel, and there is no sedimentation forecast method specifically for the non-excavated harbor basin channel. [0004] There are many forecast methods for excavating the channel of the harb...
