北京（密云）地应力监测孔钻探技术

Drilling Technology for Ground Stress Monitoring Borehole in Beijing

摘要:

地应力监测钻孔既要满足岩心地质力学测试又要达到孔内实验仪器安放的要求，其钻探质量要求高，施工工艺较常规固体岩心钻探施工复杂。以北京市密云县园林东路1号地应力监测孔钻探施工为例，介绍了北京地区地应力监测孔钻探施工技术。

Abstract:

Ground stress monitoring hole should not only meet the conditions of core geo-mechanics test but also satisfy the requirements of experimental instruments placing, the construction is more complicated than common solid core drilling. Taking the example of a ground stress monitoring hole in Miyun, this paper introduces the drilling construction technology of ground stress monitoring hole in Beijing.
