摘要
围压加载试验是空心包体式钻孔三向应变计地应力测量中配套进行的一种重要试验。详细推导了围压加载试验测定弹性常数的计算公式,并且利用它的试验成果对解除应变值进行修正,使地应力实测成果的可靠性更高。附有实例。
The confining pressure test is an important and essential test to geostress measurement with hollow inclusion triaxial strain gauge. The calculation formulas of elastic modulus to participate processing of measured data are derived minutely based on the test data. The release strains are corrected to achieve greater reliability of measured geostress results by using the results of confining pressure test. A practical example is presented to show the availability of the study result.
