The formation cause of concrete crevice on the upper＆down stream clam surface of the three gorges project is complex, and who should bear the responsibility is difficult to precisely mark off. The survey and trealment project of the crevice has the chacracteristics of intense time limit, great difficulty and numerous items. The best way to solve this kind complex compensation issue is mutual shams on the basis of respomibility compartmentalization.
