Improvement method of node-oriented measurement technique for
dynamic centrifuge modeling
Dynamic centrifuge modeling has become a generally domestic and international acknowledgement of advancement and effectiveness in geotechnical earthquake engineering. However
its realization of superiority is inseparable from reliable measurement techniques. The common failure forms of node-oriented measurement techniques in dynamic centrifuge modeling are summarized
including discussing three types of conventional node-oriented transducers for pore water pressure
acceleration and displacement to increase reliability of test results by optimizing design and improving measurement. Via separable configuration
the emergency capability and controllability of pore pressure transducer are enhanced while the saturation quality and rate of porous stone using new technique of vacuum deionized-water saturation are advanced. The workability of accelerometer with utilization of core element increased rises using a type of separable configuration; and a rubber cover seal technique is established to reduce probability of settlement and inclination during seismic loading. A combined measurement technique of accelerometer and displacement transducer is proposed
be able to gain high accuracy of internal lateral soil displacement variation with better flexibility of placement.
