The patterns and mechanism of interaction between reinforcements and soils vary with the reinforced structure as well as different parts of the same reinforced—structure. thus the corresponding testing method of interface parameter between reinforcements and soils (IPRS) are different. Based on the updated researches about testing methods of IPRS at home and abroad
and in view’ of the requirement of engineering practice
a criterion used to select reasonable method for testing the IPRS is set up in accordance with the relationship between reinforcements and soils; and some references are given in obtaining IPRS both for reinforced engineering design and researches.
