| Abstract: | The effect of changed stress state of foundation's earth and of changed groundwater state (caused by digging foundation trenches) on the calculation of earth pressure was thoroughly analyzed. It is suggested that calculation of both active and passive earth pressures should be based or strength indices determined by lateral pressure reduction experiment and load experiment methods. |
