Cause Of Formation & Water Conservancy Technical Application Research Of Crevasse Clay In Shan Dong Province, China

" Cause of formation & water conservancy technical application Research of Crevasse Clay ", is the author near for 20 year work experience summary. After retrieval, before also nobody has conducted this aspect system research, therefore many viewpoints all are first time propose. In the practice process, myself discovered yellow exudes silts alluviation the region of no relief one kind of high liquid limit clay, the hydrology geology and the engineering geology characteristic is extremely prominent, because its crevasse grows extremely, very many characteristics all with crevasse related, our water conservation person chooses a name it is "the crevasse clay". As a result of to the crevasse clay understanding insufficiency, the project processing plan is from the very beginning inappropriate, in the construction once appeared the cross body subsidence, collapses slides the dehiscence, the reclamation roller compaction is difficult, in the movement the dam base had the strong centralism leakage, serious seepage distortion destruction and so on question, affected to the reservoir normal operation, further constructed the hydraulic engineering for the Huanghe River flooded area the feasibility to bring the question.Myself pass through the repeatedly practice to know that, summarizes the crevasse clay to have the low dry weight density, the high compression, the special dispersivity, is weak - medium dives the potential expansibility and the medium water permeability, the weak impervious stability, the low shearing strength and so on, basically has found out the crevasse clay crag earth project nature, thought this has a series of engineering geology question basic reason. And further gets to the root of the new moon source, analyzes the crevasse clay to have these characteristics the reason, solved has puzzled the water conservation colleague since long ago the difficult problem, had the high theory significance and the practice significance, the crevasse clay special engineering geology nature and some crucial physical mechanics parameter which in the...
