摘要
根据近10年来我所做过的省内外25个水利水电工程65组砂浆与岩石胶结面抗剪试验资料的整理分析,将“胶结面”抗剪状况,按块状人工凿平面、块状原裂面和片状原裂面等几种类型进行了归纳分类,并给出相应的抗剪断试验指标。认为用砂浆与岩石胶结面抗剪断峰值强度作为取值标准,匹配相应的抗滑稳定计算公式和安全系数,或用抗剪断峰值强度乘以折减系数,对各类中、小型工程的设计计算都是可行的。
Through analyzing 65 groups of our data of the shear tests of sticky connecting planes between mortar and rock which were sampled from 25 hydraulic projects and were finished by our institute in recent 10 years, this paper classifies the shear status of the sticky connecting Planes into artificial cut plane, block or schist initial fracture plane and others, and presents their corresponding indexes of shear tests. It has been pointed out that taking the maximum shear strength of sticky connecting plane between mortar and rock as the standard of value and utilizing a suitable formula of stability against shear forces anda safety coefficient or timing the maximum shear strength with a coefficient of deereasement are practical and available to the computation of the designs of various small or middle-sized hydraulic projects.
