The measurement principle and methodology of tension infiltration meter are introduced,and the saturated conductivity of artificial-filled soil measured by the infiltration experiment in Panyuan is compared with that measured by soil infiltration meter.

By using tension infiltrometer,this paper studied the amount and vertical distribution of macropores with the radius of ≥0.

scientific solution of equivalent seepage tensor of rock mass,abbr.

anisotropic seepage characteristics of the limestone aquifers, using back -calculation and finite analysis methed (FAM) , it obtains the seepage tensor of the rock mass Then ?the quantitative calculations of the possible amount of seepage for the inter -river land mass at different storage water lev.

With the field survey of rock mass structural faces as the basis, the discrete mediator permeation model is set up, a calculation of the REV(Representative Element Volume) equivalent permeation tensor is conducted, and the boundary element method is used to simulate and investigate the underground drainage effectiveness of different permeation tensor conditio.
