本文介绍和分析了电力设计系统所进行的若干岩石基础试验,侧重介绍各试验的特点和分析与其相应的岩基抗拔力变化的机理。同时简介试验单位岩基应用情况及经验。从各试验中择取的岩体破坏上拔力与规范计算值比较,说明绝大多数试验值偏离规范计算区间值,提出要真正解决岩基中岩体抗拔力问题需从理沦上找途径。
This article describes and analyzes a number of rock-based tests performed by the power design system, focusing on the characteristics of the tests and the analysis of the corresponding rock-base pull-out force change mechanisms. At the same time, the application situation and experience of the rock foundation in the test unit will be introduced. The comparison between the calculated pull-out force of the rock mass and the calculated value from the tests shows that most of the test values deviate from the normative calculation interval values, and it is necessary to look for the solution to the problem of rock pull-out resistance in the rock foundation. way.
