Title:
HORIZONTAL CONTINUOUS MEASURING METHOD FOR SOIL MASS PARAMETERS OF SOFT SOIL SITE
Document Type and Number:
WIPO Patent Application WO/2021/000345
Kind Code:
A1
Abstract:
A horizontal continuous measuring method for soil mass parameters of a soft soil site. The measuring steps are as follows: soil mass strength measuring devices are arranged at the front end of a towing device; soil mass strain softening relationship measuring devices are arranged at the bottom end of the towing device; an interface friction parameter between a soil mass and a structure is measured; and the towing device actively or passively walks in a soft soil layer, a part of the towing device in walking is ensured to penetrate into a soil layer to be measured, and the penetration depth of the towing device is controlled by adjusting balance weight above the towing device and a towing angle. The method breaks through the limitation that the horizontal continuous soil mass parameters cannot be obtained by a conventional single-point vertical measuring method, and can accomplish the horizontal long-distance continuous field measurement of the parameters such as the soil mass strength, the strain softening, and the interface friction effect between the soil mass and the structure by means of a one-time towing test.
