一、前言在固体力学中,固体材料抗压强度是指固体试件在压机上受压破坏时,压机对试件所加的单位面积压力。当今国内外岩石力学界、岩体力学界、材料力学界,都循用这个定义。称如此测得的抗压强度为普通抗压强度。地壳岩体中古构造运动的应力场残留至今的残余值,为古构造残余应力。作者在中国迁西地区(1959)和中国西南部(1991)测得了此种应力;雷拉特(1962)、欧伯蒂(1966)、汉丁(1967)、福利得曼(1967)、丁克霍斯(1967)、霍斯金(1970)、耶格(1972)、思沃 I. INTRODUCTION In solid mechanics, the compressive strength of solid materials refers to the pressure per unit area imposed on the test piece by the press when the solid test piece is crushed under pressure on the press. Nowadays, rock mechanics, rock mechanics and material mechanics both at home and abroad follow this definition. The compressive strength measured as above is said to be ordinary compressive strength. The remnant values ​​of the stress field in the Middle Tectonic movement of the crustal rock mass to date are the residual tectonic residual stress. The authors measured this stress in the Qianxi area of ​​China (1959) and southwestern China (1991) Hawes (1967), Hoskins (1970), Ye Ge (1972), Siwo
