Rockfill density measuring method based on additional mass process theoretical measuring plate

Abstract

The embodiment of the invention provides a rockfill density measuring method based on an additional mass process theoretical measuring plate. The rockfill density measuring method comprises the following steps: establishing a vibrating volume line graph under a wet density-vibrating mass coordinate system and a moisture content line graph based on vibrating mass, rockmill density, wet density, vibrating volume, dry density and moisture content of each measuring point on a rockmill body based on historical engineering test data; establishing a parameter peer relationship between the rockmill density and the wet density, and performing gridding coverage on the vibrating volume line graph and the moisture content line graph to obtain the additional mass process theoretical measuring plate; selecting a measuring point on a to-be-detected dam rockmill body, acquiring rockmill rigidity K and vibrating mass M of the rockmill body through the additional mass process, enabling the rockmill rigidity K and vibrating mass M to match with the corresponding vibrating volume Vo and the moisture content w on the additional mass process theoretical measuring plate, and obtaining wet density rhp anddry density rhp d of the rockmill body based on the vibrating volume V0 and the moisture content w.

Description

technical field [0001] The invention relates to the technical field of engineering geophysical exploration, and more specifically, to a method for measuring the density of rockfill bodies based on the theoretical measuring board of the added mass method. Background technique [0002] During the construction of rolling earth-rockfill dams, in order to ensure the construction quality, it is necessary to control the compactness of each layer of rockfill material after rolling. Especially for high earth-rock dams that have been built or are under construction, due to the high dam height, the settlement deformation of the dam body is relatively large, and the design seismic intensity in the area is high. According to the regulations, the compactness of rockfill materials should take the minimum value of the design porosity, that is, the compactness of filled rockfill materials should be as high as possible, which also puts forward higher requirements for construction quality. ...
