Research on the Dynamic Responses of Shallow-Buried Depth Tunnel under the Action of Rayleigh Waves
Bursting Test Earthquake Dynamic Response Finite Difference Method Rayleigh Waves Shallow-Buried Depth Mountain Tunnel
2011/10/1
It has been proved by the seismologic observation of 5.12 Wenchuan Earthquake that a large number of shallow-buried depth mountain tunnels at the portal are underwent severe damage. Earthquake waves, ...
Load Calculation Method of Tunnels with Shallow Buried Depth and Unsymmetrical Pressure in Regions of Weak Fissured Surrounding Rock
Lining Load Numerical Calculation Tunnel with Unsymmetrical Pressure Weak Surrounding Rock
2011/5/1
The key problem of supporting structure design is the load calculation in tunnels with shallow buried depth and unsymmetrical pressure in the situation of weak surrounding rock. The results of simplif...
Quantitative determination of long-term erosion rates of weathered granitic soil surfaces in western Abukuma, Japan using cosmogenic 10Be and 26Al depth profile
weathered granitic soil surface erosion rate cosmogenic 10Be and 26Al depth profile sampling depth
2010/8/9
We present erosion rates of granitic soil surfaces in the western Abukuma upland, Japan using depth profiles of in-situ produced cosmogenic 10Be and 26Al based on physical parameters for both neutron ...
Tight coupling UFMArcGIS for simulating inundation depth in densely area
Tight coupling UFMArcGIS simulating inundation depth densely area
2010/7/14
The integration of hydrological models and Geographical Information Systems (GIS) usually takes two approaches: loose coupling and tight coupling. This paper presents a tight coupling approach within ...
Bedrock Depth Mapping of the Coast South of İstanbul: Comparison of Analytical and Experimental Analyses
site response microtremor resonance frequency bedrock depth İ stanbul
2009/7/7
Local S-wave velocity-depth profiles and bedrock depth distribution are key factors in assessing seismic hazard and earthquake ground motion characteristics since they allow determination of the ampli...
