THREE NEW RESEARCH DIRECTIONS WORTHY OF ATTENTION IN ENGINEERING GEOLOGY FIELD——TO COMMEMORATE THE 60TH ANNIVERSARY OF CAS ENGINEERING GEOLOGY LABORATORY

It's well known that engineering geology has been playing an important role in the engineering construction of our country. Particularly, the authors have noticed that more and more importance has been attached to the three research areas of rock weathering, ancient geological engineering and geological disaster prevention and control. These three new research directions appear respectively, corresponding to the test and evaluation of rock weathering velocity, the research on engineering geology mechanics of large ancient underground caverns, and the mountain tourism planning served engineering geology method for prevention and control of the geological disasters of mountain tourism.
