các bác dịch hộ em câu nay trôi chảy nhé:
" When an underground excavation is made in rock mass, the stresses which previously existed in the rock are disturbed, and new stresses are induced in the rock in the immediate vicinity of the opening. One method of representing this new stress field is by means of principal stress trajectories which are imaginary lines in a stressed elastic body along which principal stress act. Before considering in detail the distribution of stresses around single underground excavations of various cross-sections, it may be helpful to the reader to visualise the stress field by making use of the approximate analogy which axists between principal stress trajectories and the streamlines in a smoothly flowing stream of water."
