Description

Technical Field

[0001] The invention relates to a method for monitoring natural mud surface settlement during the whole process of dike (dam) construction in water area construction monitoring, and in particular to a system for monitoring settlement during the whole process of dike construction and a monitoring method thereof. Background Art

[0002] During the construction of the embankment, it is necessary to monitor the settlement of the natural foundation under the embankment. According to the change analysis of the settlement amount and settlement rate, it is judged whether the foundation is in a safe state during the construction of the embankment, dynamically guide the construction, and control the loading progress of the embankment construction. On the other hand, the measured settlement is also the basis for calculating the actual amount of engineering materials at completion, providing data support for the project cost accounting, and providing a reference for the pre-settlement value of similar projects.

[0003] At present, the foundation settlement in the project is generally measured by leveling rods and leveling instruments. Engineering leveling can only measure elevation on land. The construction of the dike is usually divided into three parts: one part is underwater, another part is in the tidal level change area, and another part is above the water surface. In the early stage of the dike construction below the water surface, it is impossible to use conventional settlement monitoring methods to implement measurement and monitoring due to multiple factors such as construction ships, wind and waves, and water currents. At present, settlement measurement can only be started after the dike is exposed to the water surface. The measured settlement data lacks the settlement amount in the early stage of construction. As a result, the designers are unable to analyze the early settlement trend of the underwater part and calculate the early consolidation of the foundation, which is not conducive to the development of construction production and scientific research. When the project is completed and settled, there is a lack of early settlement data. How to estimate the increase in engineering volume caused by this part of the settlement has become a difficult problem.

[0004] To solve the above problems, we made a series of improvements. Summary of the invention
