Soil Mixing Wall can meet the needs of foundation pit support structures in various projects. Compared with other supporting structures, it has the advantages of good permeability resistance, short construction period, and less impact on the surrounding environment. It is a foundation pit supporting structure with great development potential^[1].

Research on the Overall and Local Mechanical Behaviors of Steel Box Girder Cable-Stayed Bridge via Incremental Launching Construction

Piyun Zhang, Xinwen Jiang, Huilian Gan — Sat, 21 Oct 2023 00:00:00 +0000

In this paper, a large-span cable-stayed bridge with double pylons and double cable planes is employed to study the overall and local mechanical behaviors. The steel box girder bridge is constructed by incremental launching with the maximum span of 50 m. Through the overall stress analysis, the most unfavorable stress position of the structure in the incremental launching construction is identified; the refined local stress analysis is carried out for the girder section at this position, and the local stress characteristics of the structure are studied. The mechanical performance and the applicability of incremental launching are determined by comparing four kinds of elastic cushion. This paper aims at improving the safety of incremental launching construction of steel box girder bridge, and can provide reference for similar projects.

Deqiang Liao — Sun, 22 Oct 2023 00:00:00 +0000

With the rapid development of economy in China, building technology has been improved and innovated in recent years. Urban development cannot be separated from buildings. However, China’s land resources are limited and cannot meet the increasing housing needs. More and more real estate companies have shifted their investment focus to high-rise building projects, which are more complex and require a lot of building materials than lower-rise building projects. In recent years, with the optimization and upgrading of technology, the requirements of high-rise buildings are getting higher and higher, and the technical operation is becoming more and more difficult. In this case, appropriate methods must be taken to control the technical quality of civil engineering.
