| Abstract: | On the basis of the research on stress transfer of flyash piles, the distribution law of frictional resistance is analysed, and with the help of the Mindlin solution and the assumption of the simplified distribution form of frictional resistance, a formula is derived for calculating the additional stress in compound foundation. Which is a more reasonable method for calculation of settlement of compound foundation. |
