Abstract

In recent years, movable dam has been studied and applied effectively in the Mekong Delta. The stability principle of the dam is to expand the bottom of the structure to reduce the normal stress so that it can be placed directly on soft clay soil without reinforcement or little reinforcement. Characteristics of the movable dam are the horizontal loads and torque greater than the vertical load. Therefore, the problem of sliding stability of movable dam is very important. This article introduce the method of constructing the limited load envelope of the movable dam foundation on soft clay soil. The limited load envelope no dimensional of the movable dam is used in calculating the movable dam on the soft clay soil.
