首先,应用 Venedikow 调和分析方法计算体应变仪观测记录的M2波视潮汐因子;然后,对体应变仪井下传感器观测层岩芯进行单轴压缩试验,根据应力-应变曲线求取岩芯试样的力学参数。对比研究试样的单轴抗压强度和弹性模量与M2波视潮汐因子的关系,结果表明,弹性模量E对M2波视潮汐因子有明显的影响,随着M2波视潮汐因子的增大,岩石弹性模量呈线性函数降低,二者具有很好的相关性。钻孔岩芯力学性质的差异性是造成体应变仪之间M2波视潮汐因子差异较大的主要因素。"/> To obtain the relationship between M2 apparent tide factors and mechanical properties, we first use the Venedikow analysis method to calculate apparent M2 tide factors. Then, uniaxial compression test is carried out on the core of the observation layer of the borehole, and the mechanical parameters of the sample are obtained according to the stress-strain curve. We observe the effects between M2 apparent tide factors and the uniaxial compressive strength and elastic modulus. The results show that the elastic modulus of the borehole has obvious influence on M2 apparent tide factors, and with the increase of M2 apparent tide factors, the elastic modulus of rock decreases in inverse power function, and the two have a good correlation. The main factor of the mechanical properties of borehole leads to the great difference of M2 apparent tidal factors for body strainmeter."/> 岩石弹性模量对钻孔体应变仪M<sub>2</sub>波视潮汐因子影响分析
