The instantaneous, average, and critical speeds of vehicles passing through the Kamchik pass were determined in this article. law safe movement traffic flow has been developed. research results on determining speed different categories mountain conditions are presented. To ensure safety, depending condition road surface dangerous areas road, recommendations given limits signs to be installed.

After the wenchuan earthquake, dynamic response law of rock slope under action load is a very concerned and urgent problem in field seismic engineering. This paper analyzed simplified cosine wave by numerical simulation with FLAC3D software. research emphatically variation amplification coefficient displacement, acceleration velocity condition different height, angle, period amplitude, which pr...

Creep is an important factor of muddy submarine channel slope instability. In this study, a sub-bottom profiler was used to monitor the continuous internal change in laboratory better understand creep characteristics and mechanism The process analyzed according changes sound intensity. results indicate notable during instability process. Changes intensity time series decrease with increasing de...
