We have confirmed that most of artificial pile foundations have not been arranged at reliable bearing layer,some measures have been used to dispose the ground ,for example, to grout the caves in soil by drilling ,to grout the weak contact belt and reinforcing it by sub-high pressure cleavaging it,to fill the karst ditches,trenches and caves by grouting high density cement or cement-soluble gla.

Analysis on influence of weak fractured zones on deformation and stability of a right dam-abutment by FLAC~(3D);

The dynam relaxed rockmass at Daliushu in Heishanxia Gorge on the Yellow River contains a great quantity of weak intercalations, which control the dynam relaxed rockmass physical and mechanical properties to a great extent.

Study on evaluation of deformation modulus of no clay weak interbed;

Through analysing the correlation between physical property of no_clay weak interbed obtained by in_situ test and its existed geostress,and combining the confining pressure simulating test results of disturbed weak interbed sample,we show that the controlling effect of confining pressure to physical property of no_clay weak interbed is very evident,as the same of clay weak interbed.
