Technology Probe and Research
An Example of Consolidation in Large Area of Soft Clay
Han Shaoying, Zhao Zaili
2016, 30(3): 124-128. doi: 10.3969/j.issn.1007-2993.2016.03.004
[Abstract](59) [PDF 823KB](16) [Cited by] (1)
Abstract:
The principle of preloading consolidation method is that the foundation soil under the load actions(with an increasing total stress σ) can increase pore water drainage(i.e.,reducing the pore water pressure μ) and effective pressure σ'.This paper introduces the design and construction methods to cond...
Research on the Algorithm of Architecture Data Extraction Based on Airborne LIDAR
Yan Liang, Xu Jiaohuang
