SeisOpt® ReMi®: Derive one-and two-dimensional S-wave velocity from ambient (passive) and or active source using a typical seismograph and standard refraction geophones.
New version of ReMi can analyse Love waves in addition to Rayleigh waves, active and passive signals and has an automatic inversion module.
Non-linear arrays are also handle within the geometry module.
ReMi can be used for:
- Site response
- Liquefaction analysis
- Soil compaction control
- Pavement evaluation
- Mapping the subsurface and estimating the strength of subsurface materials
- Finding buried cultural features, such as dumps and piers
ReMi can economically and efficiently determine the IBC seismic soil classification at a site. It uses ambient noise and/or active source signals to determine average S-wave (shear-wave) soil velocities to more than 30m (100 ft) depth. Velocities as deep as 1000 ft have been obtained from ReMi measurements. These velocities are used to classify a building site with the IBC site class A through E. Since it requires no artifical source ReMi is ideal for S-wave studies in urban areas and construction sites.
The IBC Code 2006 recommends determining the soil classification at all building sites. Until now, it has not been economic for all builders to do so. ReMi provides an inexpensive and efficient way for all builders to meet the IBC recommendations. In addition it can also be used for:
