Abstract：For resolving controversy of separate and combined calculation of water and earth pressures and theoretically proving that combined calculation of water and earth pressure is reasonable under some circumstances，it is necessary to establish a unified algorithm that is able to integrate separate and combined calculations in a theoretical framework. This paper establishes a unified calculation theory of water and earth pressures through the ideal model test and verifies its scientificity at the same time. Based on the ideal model test，a new strength theory is proposed that can be applied to the unified algorithm. From the calculation example we can see slight differences between the results of new and traditional methods. This new unified algorithm can be used to calculate water and earth pressures separately for sand and change to combined calculation for clay. Moreover，this can also be applied to calculate the water and earth pressures for aquitard strata like clayey silt and silty clay. It provides a theoretical basis for the calculation of load on underground structures.
