On the basis of summarizing and analyzing the existing treatment measures for the soft foundation of railroad in China, combining with the result of the load test for composite foundation and the observations obtained on site, a comprehensive treatment measure for the complex soft foundation at the Laoguochang-Liziguo section of new built Neikun railroad is put forward in the paper
This paper examines comprehensively the defects lying in K210+701—+900 of the Chengdu-Kunming Railway and takes the treatment of gravity retaining walls and other treatments.
In view of complex geological conditions, we have taken many methods and some comprehensive processing measures in the construction, so that guarantee designed demands and engineering quality.
For example of a project, judging from production operation and economic benefits, this Raper explains the necessity of regulated gasflow and effective measures to solve gas flow regulation is put forward, different measures are compared in technology and economy.
The rock foundation of the dam of the Dahua Hydro-project was relatively poor, however, both the uplift and water leakage under the dam are fairly low after a comprehensive foundation treatment. A few years' observation indicates that the effect of foundation treatment is remarkable and the uplift is lower than the designed. The paper points out the problems encountered in the design and suggests that the favorable factors of fundation treatment should be considered in future.
Emergent cerebrovascular dissease is one the three death causes in the world. This paper investigates 60 cases of emergent cerebrovascular disease and then analyzes their inocidence, risky factors, treatments, status after recovery and mortality, respectively. Based on the anakysis. a series of preventions from emergent cerebrovascular disease is proposed to avoid risky factors relaed to the disease,and a set of comprehensive treatments on emergent cerebrovascular disease is also discussed in this paper.
Vertical hight of excavated slope in left bank is over 200 m at Baozhusi hydropower station. The geological conditions are complex with many faults and clay courses which form over ten sets of unstable wedge rock mass. According to different geological conditions combined treatment measures,such as shear concrete plug,anchor bar pile,system anchor rod and blasting control,are taken to ensure the stability and safety during construction and follow the construction schedule. Taking the Baozhusi project as an ...
