摘要： 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.

摘要： An adjustment method of moisture content and dense state for a hydrogel improved subgrade based on weather-resistance during an in-service period, including: step 1: carrying out surface cleaning and compaction of ground; step 2: preparing hydrogel improved subgrade raw material; step 3: paving the prepared material on the surface to form first-layer improved subgrade; and step 4: paving plain soil subgrade onto the first-layer. The method combines the water absorption and release function of the modified resin and the characteristic of the gel state thereof, to pave the improved subgrade in layers, which can absorb water and slightly expand when the water content in the subgrade is increased to a certain threshold value, and a strength and compactness protective layer can also be formed at the connection sections of the ground and the subgrade, and the subgrade and the pavement, to prevent the pot-cover effect from occurring.

摘要： 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.
