According to the results of the field plate load test, the characteristics of geotechnical engineering...
Deep Fill Layer with Sizable Area Foundation Treatment Technology for Tall Buldings
Chen Jianmin
2014, 28(5): 237-242. doi: 10.3969/j.issn.1007-2993.2014.05.006
[Abstract](52) [PDF 1055KB](10)
Abstract:
With the development of urbanization in China, the high quality construction land has been significantly decreased. Rational utilization of defective land resources is a great subject of urban development faced at present. In urban expansion process, we often meet sandstone pit or weak soil area, an...

Abstract:
In this paper, the definitions of open and closed boundary are presented firstly. The differences of both are discussed. Through three samples,the reason for open type boundary being better than closed boundary in reinforced effect is analyzed. Then,it is shown how to convert closed boundary into op...
Effect of Groundwater on Sand Slope Stability
Zhang Xiaocheng
2014, 28(5): 257-260. doi: 10.3969/j.issn.1007-2993.2014.05.009
[Abstract](68) [PDF 4943KB](11)
Abstract:
Inner Mongolia in winter snow is thick, the spring temperatures rise quickly, a lot of snow water in slope and retaining wall back in fine sand layer. Due to the drainage hole at the upper part of the lower slope and retaining wall most jam, water can not be discharged. Melting snow along the slope ...
