内容記述(抄録等)
The consoiidated undramed compression tests were performed for the exper iment of shearing properties of compacted mixed soil with tuffaceous sand and clay under non-adsorbed and adsorbed condition. The following results are obtained from these tests.
(1) The pore pressure coefficient A_f of the mixed soil is relatively greater than normal compacted clayey soils.
(2) The shearing strength is decreased by adsorption over 10% wet side of optimum moisture content W_<opt>.
(3) The shearing parameter for effective stress c^' and φ^' is constant for wet side of W_<opt> eventhough the compacted moisture content and adsorbed condition are changed.
