现场岩体变形试验刚性承压板法的影响因素

承压板法是一种通过刚性承压板施力于半无限空间岩体表面,测量岩体变形,并按均匀、连续、各向同性的半无限弹性体表面受局部荷载的布西涅斯克（Boussnieq）公式计算岩体变形特性指标的方法.广泛应用于大中型水利工程,是比较常用的测定岩体变形参数的方法之一,具有理论成熟,方法可靠,试验周期短,人员劳动强度小,费用较低等优点.本文通过对刚性承压板法影响因素的分析,设计出最佳的试验方案,做到多快好省,为设计部门提供更为可靠的资料.

Effect Factors on Rigid Bearing Plate Method in Deformati

Bearing plate method is a kind of method of putting pressure on the surface of rock in semi -infinite space by means of bearing plate , measuring rock deformation , and calculating the characteristic indexes of rock deformation by the Boussnieq formula to be satisfied with the condition that the surface of semi -infinite elastic body is even , continuous , and has the same nature in every direction. The method is widely used in large and medium - sized water projects , is a kind of methods measuring parameters of rock deformation , and has many advantages such as that the theory is well - considered , test cycle is short , labor intensity is acceptable , and the cost is low . The authors analyzed the effect factors on rigid bearing plate , and designed the optimal scheme of test so as to do more , faster , better , and cheaper , and to provide more reliable data for design departments .
