Abstract: The structure has a subgrade or slope to be monitored and strip-shaped smart geosynthetic material compound devices. The strip-shaped smart geosynthetic material compound devices are buried to run through a subgrade or slope predicted slip crack surface. Gaps between the strip-shaped smart geosynthetic material compound devices and borehole inner walls are filled so that the force environment of the strip-shaped smart geosynthetic material compound devices is close to the subgrade or slope internal environment. Each strip-shaped smart geosynthetic material compound device has a strip-shaped geogrid, lead, and heat shrinkable tube. The lead is arranged in a length direction of the geogrid, and the lead and geogrid are fixedly connected at an interval of a set distance, with each fixed point forming a measuring point. The geogrid is wrapped in the heat shrinkable tube, and a free end of the lead is drawn out of the heat shrinkable tube.

Abstract: A method and system determines in real time the bearing capacity of a foundation tamped by a high-speed hydraulic tamper. Four wireless acceleration sensors are arranged uniformly along tamping plate edges, sensor position tamping points are determined; the soil is tamped, the plate peak acceleration slows, tends to, and reaches stabilization in a range, a relationship curve between the tamping number and plate peak acceleration is determined; different loads are applied to the foundation to obtain corresponding settlements, coordinate axes are established, points are drawn according to each test data group and sequentially connected with a smooth curve to obtain a settlement-load curve, and the curve is fitted; a tamping number and foundation bearing capacity relationship is obtained; the two relationship curves are combined to obtain a relationship curve, and the foundation bearing capacity magnitude at a certain moment during the tamping operation is determined by using the acceleration index.
