ABSTRACT

With the rapid development of our country's transportation infrastructure construction, the highway construction has become an important support for the economic development. One of the core structural elements of expressway is roadbed, whose quality directly affects the overall quality, durability and safety of highway engineering during construction and operation. In the process of subgrade construction, the speed control of filling operation and the time sequence arrangement of each level of road construction are highly dependent on the monitoring and prediction of subgrade settlement. Both the immediate settlement during highway construction and the long-term settlement after completion have a direct impact on the construction quality and safety performance of the project. Therefore, the scientific monitoring and accurate prediction of subgrade settlement will play an important role in controlling the settlement during the filling period and the settlement after construction. As a key component of highway informatization construction technology system, subgrade settlement prediction is not only a technical challenge, but also a key strategy to ensure project quality. Therefore, strengthening the prediction ability of subgrade filling stage and settlement after completion, especially for sections under special geological or design conditions, and flexibly adjusting construction plan and optimizing operation sequence according to the prediction results, is one of the effective ways to ensure the timely and quality completion of the project and improve the overall safety performance. This methodology not only reflects the refinement and intelligence of construction management, but also is an indispensable part of modern highway construction. Based on the technology of embankment settlement monitoring and construction control, this paper discusses the quality of embankment settlement monitoring and the concrete application of construction control technology through detailed theoretical analysis. Combining grey system theory, settlement observation method and soft soil subgrade settlement control technology, this paper aims to put forward a set of scientific and effective settlement monitoring and construction control system to provide theoretical support and technical guidance for highway construction.
