This paper presents the results of two lateral loading tests on the actual caissons of the same size, which were constructed about 40 years ago, as well as the results of corresponding numerical analyses. In the tests, much focus was placed on the proportion of the lateral resistance between the side friction of the caisson and the passive soil resistance. The test results show that the proportion of frictional resistance to the total resistance is relatively large, and the evaluation of the friction is important. Numerical analyses were also conducted to examine the applicability of the conventional non-linear method. The caisson behavior obtained from analyses give reasonable agreements with the measured results, if adequate coefficients of lateral subgrade reaction are chosen.
