Locale Experiment Study And Dynamic Optimized Analysis Of Aseismatic Disposal Measure Of Roadbed Of Soft Soil Nipped Sand

Series of problems about the stability of the foundations caused by the earthquakes, such as seismic, settlement liquefaction etc. As in the course of liquefaction the intensity of foundations may be lost and the foundation may be totally damaged, we must attach great importance to the liquefaction. With the rapid development of the society and many more soft foundation problems, people now pay more attention to the seismic settlement of soft clay.Based on the project of Shanfen high speed way in Guangdong,we launch the room and site experiment for roadbed of soft soil nipped sand in this paper, we studied some foundation improvement measure and compared with each other in respect of physics mechanics character, site experiment parameter and distinguish index of liquefaction experimentation. And finally, we distinguish these methods based the analysis of construction settlement.We also make the calculation of the FEM in with indoor data, then we detrude safety factory of anti-liquefaction, vibration shearing strength and level vertical displacement of these improvement measure on tie condition of earthquake, we could determinant these methods after series analysis of the results. In the end,we obtain the optimized project after rationality analysis to vibrational detritus stake.
