The Dajilin River Reservoir is located in the Xilin Gol League of the Inner Mongolia Autonomous Region. Commissioned by CR Power (Xilin Gol) Water Co., Ltd., our company undertook the displacement monitoring of the Dajilin River Reservoir Dam.
The monitoring system included:
1. A vertical displacement reference network comprising 5 reference points (K2–K6), observed 4 times;
2. A horizontal displacement control network composed of 7 reference points (GPS1, GPS8, and K2–K6), also observed 4 times;
3. A settlement monitoring network consisting of 19 cross-sections. Cross-sections 1 and 19 each had 3 horizontal and vertical displacement monitoring points, while cross-sections 2–18 each had 4 monitoring points. In total, 148 horizontal and vertical displacement monitoring points were installed.
Horizontal and vertical displacement monitoring shared the same cycle, with a cumulative total of 1,628 monitoring point-times completed.
Fieldwork for displacement monitoring commenced on September 28, 2021, and concluded on July 29, 2024, spanning 1,035 days. Data compilation and submission of all deliverables, including technical reports, were completed in April 2025, successfully passing the owner’s acceptance review.
