新型单向岩体应力,应变匹配系列传感器的研制

新型单向岩体应力、应变匹配系列传感器，是最新研制的应用于岩体及相似材料模型等压力、变形量测量的匹配型系列传感器，其弹性元件的弹性模量与被测岩体的弹性模量相等，是岩体应力、应变定量测量型传感器它可以同时测得岩体被测点的压力和变形量，其测量范围为硬岩、中硬岩体、软岩、具有一定弹性模量的相似材料和土壤等的应力、应变测量经过在井筒及其围岩和相似材料模型上的应用，其重复性、稳定性等技术指标满足了岩体和相似材料模型的测试

DEVELOPMENT OF A SERIES OF NEW TYPE OF SENSORS FOR UNIDIRECTIONAL ROCKMASS

A series of new type of sensors are developed which are used in rockmass and in models of equivalent materials to measure ground pressure and deformations.The elastic modulus of the elastic elements is equal to that of measured rockmass.The stress and strain of the rockmass in the measuring points can be quantitatively measured.The sensors can be applied in hard,medium hard and soft rocks as well as in models made of equivalent materials of certain elastic modulus or soils.They were used in shaft and models of equivalent materials,and the repeatability and stability,etc.can satisfy the requirements of tests made in the rockmass and in equivalent materials.
