Abstract

The invention relates to the field of geotechnical engineering study and aims to provide a one-dimensional vertical dredger fill particle concentration testing device and a testing method. The one-dimensional vertical dredger fill particle concentration testing device comprises a settling column, a supporting system, a measuring system and a monitoring system, wherein in the supporting system, a measuring cantilever is mounted on a vertical supporting steel plate; the measuring system comprises an X ray emitting device and an X ray receiving device which are mounted at two ends of the measuring cantilever respectively, and the settling column is vertically arranged between the X ray emitting device and the X ray receiving device; the X ray emitting device and a driving motor are connected with a computer through signal wires respectively; the X ray receiving device is connected with a data acquisition device and the computer sequentially through signal wires. By means of the one-dimensional vertical dredger fill particle concentration testing device, settling layering conditions of dredger fill samples in all time periods can be observed directly, and precise data can be obtained by the data acquisition system for further study. The device is simple in structure and easy to use, the settling column is easy to dismount and clean after an experiment, data can be recorded automatically, labor demanded by the experiment is reduced, and artificial reading errors are reduced.

Description

technical field [0001] The invention relates to the field of geotechnical engineering research, in particular to a one-dimensional vertical dredging fill particle concentration test device and a test method. Background technique [0002] With the development of the economy and the continuous advancement of urban construction, people's demand for land resources is getting higher and higher, and the problem of land resource shortage is becoming more and more prominent. my country's existing tidal flat resources are about 2.17 million hectares, involving 12 provinces, municipalities and autonomous regions. At present, the newly-increased construction land through reclamation projects accounts for about 3-4% of the total area of ​​newly-increased construction land in the country every year, and accounts for 13-15% of the annual newly-increased construction land area in coastal provinces (districts, cities). Marine reclamation has alleviated the shortage of land resources in my ...
