| Abstract: | Analysis of ground
response curves for circular rock openings supported by rockbolts is proposed.By means of
Lamé's formula and the elastic-plastic theory,and with reference to a series of
Labiouse's articles and other ducuments the calculating programs on TURBO Pascal and Excel
are developed,and the characteristics of stress and displacement of circular rock openings
are analysed.The results obtained in this paper are more satisfactory than Labiouse's. |

| Keywords: | openings bolting stress displacement broken radius |
