| Abstract: | Based on num erous experim ental data and in-place m easurem ents, the engi- neering geologicalCharacteristicsofbaserock katam orphism area are analysed. Thelaw of overburden failure and phenom enon of underground pressure adjacent to katam or- phism area , and the m echanism and m ethods of reducing w aterproof pillars are dis- cussed. |
