Numerical Analysis of Pile-Anchor Support System in Foundation Pit
When it talks about the building foundation of urban construction projects, it is necessary to ensure the security and stability of the foundation,and it also need to ensure it does not have the frustrating effect to the environment. Traditional strength-based control design methods have been gradually replaced by deformation control theory.Because of the influence of [...]
Study on Earth Pressure of BeiLing Station Passageway Foundation Pits in Shenyang Subway Line No.2
As the rapid development of Chinese economic, many cities started to build subway projects. Subway construction involves a large number of foundation pits. Therefore, the correct calculation of the earth pressure on the supporting structures becomes a quite significant topic.The existed investigative results on earth pressure calculation are kinds of simplified calculations in which only [...]
Reliability Analysis of Supporting Structure Based on Force Balance of Deep Foundation Pit
A thorny issue popping up in deep foundation pit construction is how to ensure the stable security and reasonable costs of the supporting structure of deep foundation pit. However, in the traditional design, the security as a sole index to evaluate the stability of the deep pit is unreliable. As a result, it is a [...]
Study on Application of Steel Reinforced Concrete Support Piles in Foundation Pit
In the recent years,along with the high-speed development of city construction,a great number of high-rises are constructed together with the exploitation of the underground structure,which surely brings large-scale excavation and support of the foundation pit project. Because of the influence of the underground pipeline which have a wide distribution around the project as well as [...]
Analysis of Stability of Laterite Foundation Pit Slope in Hainan
As the construction of Hainan International Tourism Island is carried as the state strategy, the construction of matching infrastructure has been expanded in big scale. Under this situation, it is of certain directive significance for theoretical research and engineering practice to do further study on the engineering properties of the regional laterite produced from magmatic [...]
The Technical of Tunnel Monitoring Measurement Applied in the Yingzuishan Tunnel
With the rapid development of economy, there are many tunnels on the traffic line. How to eusure the stability of surrounding rock and supporting structure in the different geological conditions, detection and measurement are a key proess.In the paper, construction measurement technology on NATM is discussed in detail and methods of measurement data processing are [...]
Research on Static and Seismic Performance of Suspen-dome under Supporting Structure
Suspen-dome is a new kind of hybrid structure which is combined with the single-layer spherical reticulated shell and the cable-strut system. Suspen-dome has better mechanical properties compared to single-layer spherical reticulated shell structures, the overall stiffness of the structure gets a larger increasing because of prestress. The suspen-dome can be applied to a larger span [...]
