摘要
在现场测试的基础上，阐述了软岩巷道的围岩变形量与支护阻力的定量关系，阐明受力恶化是遏制支护阻力的基本原因，得到了实施支架壁后充填可使支架均匀承载、大幅度提高支护阻力、从而有效地控制软岩巷道围岩变形的显著效果。
Based on the field investigations, this paper illustrates the quantitative relation between the amount of surrounding rock deformation and support resistance of roadway in soft rock. The poor loading condition is the basic reasons of the supporting rest.tance being severely limited. It is found out. however, that support backfilling enables the support to be loaded uniformly, resulting in, therefore, great increase of the supporting resistance, and hence the effective control of the deformation of the roadways in soft rock.
