The invention discloses a highway slope settlement measurement method fusing GNSS and InSAR, and belongs to the technical field of geodetic survey and geological disaster monitoring, and the method comprises the steps: obtaining an earth surface dielectric characteristic fingerprint representing the electrical characteristics of a slope surface through calculation; calculating to obtain subsurface structure characteristic fingerprints representing slope subsurface structure characteristics; constructing a double-fingerprint coupling diagnosis model of a physical process for associating the earth surface dielectric characteristic fingerprint with the subsurface structure characteristic fingerprint, wherein the double-fingerprint coupling diagnosis model is configured to output a diagnosis result based on a change mode of the input fingerprint; the surface dielectric characteristic fingerprints and the subsurface structure characteristic fingerprints serve as coupling fingerprints to be input into a double-fingerprint coupling diagnosis model for calculation, and internal state parameters representing the loosening degree of the soil structure in the slope are obtained; the stability early warning information of the target slope area is generated, and the instability risk of the internal structure of the slope can be recognized in advance in a non-contact and large-area mode before macroscopic settlement of the slope occurs.

This invention provides a deep tillage, fertilization, and soil covering integrated machine. By integrating multiple deep tillage plows, fertilizer spreaders, and soil covering plows onto a single vehicle body, and arranging them in the following order—deep tillage plows in front, fertilizer spreaders in the middle, and soil covering plows at the rear—this invention achieves simultaneous completion of the three processes of deep tillage, fertilization, and soil covering in one operation. Specifically, the deep tillage plows and fertilizer spreaders are connected by the same mounting bracket. The fertilizer spreader's depth adjuster precisely aligns the fertilization pipeline with the trench created by the deep tillage plow, allowing the flaky fertilizer to fall directly into the active root zone after deep tillage. This ensures structural alignment between the fertilizer outlet and the deep tillage trench. Simultaneously, the integrated electrical control box precisely controls the release device's action according to the preset plant spacing based on distance signals from the travel time meter, achieving automated control of fixed-point and quantitative fertilization. This reduces labor costs, improves fertilizer utilization, and avoids secondary soil disturbance caused by rotary tillers.

This invention discloses an expandable diameter reinforcement device and construction method for composite cement-soil mixing piles. The device includes a steel pipe pile, a sliding collar, multiple reinforcement units, a traction rope, and a traction guide. The sliding collar is fitted around the outer periphery of the steel pipe pile. Multiple reinforcement units are spaced apart around the pile end, with each reinforcement unit's two ends connected to the sliding collar and the pile end, respectively. The traction guide is located on the inner wall of the steel pipe pile, and the traction rope is connected to the sliding collar. When the traction rope is pulled upward, the sliding collar moves towards the pile end, reducing the distance between the two ends of each reinforcement unit and driving the multiple reinforcement units to bulge outward, forming an expanded diameter reinforcement structure around the pile end. This device effectively solves the problem of difficulty in lowering large-sized reinforcement components in limited construction channels. This construction method, by implanting and simultaneously expanding the diameter of the reinforcement components in a fluid-plastic pile body, is unaffected by subsequent hardening, ensuring controllable forming quality and ultimately improving the bearing capacity of the enlarged head region of the composite cement-soil mixing pile.

The method includes: real-time monitoring of the operating data of the energy storage inverter system; establishing a historical strategy performance database; predicting the temperature rise trajectory of the filter within a preset time window based on the current filter temperature, ambient temperature, and heat dissipation status using a thermal model during grid-to-off-grid switching; using the temperature rise trajectory as a key constraint; based on the strategy performance under similar operating conditions in the historical strategy performance database; and combining the current dominant operating mode and the power supply priority of key loads, ensuring that the filter temperature does not enter a preset risk range; dynamically calculating and selecting control strategy parameters that achieve a balance between switching smoothness, harmonic suppression level, and strategy execution risk; and executing the control strategy parameters. This invention reduces strategy execution risk by dynamically outputting the globally optimal strategy through multi-dimensional coupling.
