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.
ReMi is a registered trademark and the SeisOpt® ReMi® software is the original algorithm developed from Prof. Louie for seismic site characterization using shear waves.
SeisOpt ReMi complies with the Chilean seismic construction norm DS61-2011 (Reglamento Diseno Sismico) and International Building Code (IBC) standards for site class determination
Optim through his network of representatives will provide a certification of original software purchase and training (if this option is required by the customer).
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 can also be handled 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 (or country based) 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.
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 (or country based) recommendations.
