Abstract:
Based on presented tests of improvement of solid waste ground by stone column, the failure mode of lateral expansion of column body can be found. It is assumed that solid waste surrounding column is in Rankin's positive limit situation caused by lateral expansion of column body, self weight solid waste and column is neglected, the calculation theory of limit bearing capacity of stone column can be extended on equilibrium of solid waste and column. The limit bear capacity of stone column can be calculated on parameters by complete tests and reference data. The heavy dynamic penetration tests were finished in stone column and the characteristic value of bearing capacity can be recommended on blow count. It is shown that bearing capacities of calculation and field test are close.
