| Abstract: | In regard to the high ground pressure, difficulty in supporting, and persistent deformation failure involved in the construction in soft rock, the paper advances the concept of supporting in key positions of soft rock, and meanwhile studies the supporting principles in key positions. In engineering practice, secondary support of key positions has been carried out by unequal strength coupling control and grouting strengthening technique, which has successfully put the deformation under control, and guaran- teed the security of the tunnel project. With the advantages of simplicity, high reliability, quickness in engineering and low cost, this control technology is worth generalizing in engineering practice. |
