We have developed a wireless intelligent type strainmeter for the measurement of in-situ stress. The instrument for the measurement comprises SRAM, RTC, an A/D converter, MPX, a microprocessor, and batteries in addition to a strainmeter sensor. We can install it in as 500m deep as boreholes and can easily remove by overcoring. The stress measurements by overcoring in deep boreholes are a newly developed method and we encountered some difficulties. However, we could solve these problems. In this paper we describes these difficulties and how we solved them.
