Device for measuring strength and strain softening parameters of saturated clay sample based on full-flow penetration

摘要

A device for measuring strength and strain softening parameters of a saturated clay sample based on full-flow penetration belongs to the technical field of geotechnical, geological and environmental research. The device mainly comprises two parts: an overlying pressure loading system and a full-flow penetration system. The present invention mainly aims at the problem of incomplete backflow of the soil in the measurement of soil strength and strain softening parameters with a full-flow penetrometer for saturated clay, and applies the working principle of a traditional consolidometer to vertically pressurize a soil sample to ensure the backflow of the soil, thereby improving the applicability of the full-flow penetrometer in the measurement aspect of the soil strength and the strain softening parameters and having important practical value for test research and marine engineering design.
