摘　　要：本文根据著名的詹森 (Janssan)理论和美国学者詹尼克 (A W Jenike)的基本观点 ,考虑筒仓内贮料由于某种原因 ,其料面倾斜 ,在此状态下 ,将仓内贮料分为两部分 ,斜面部分贮料作为外荷载考虑 ,而在斜面底水平面以下部分则按詹森理论分析水平压力与垂直压力 ;最后采用将斜面圆柱体部分贮料作为边界条件 ,导出在贮料面倾斜状态下 。According to famous Janssan′s theory and American scholar A.W.Jenike′s basic point,because of some reason,the surface of the bulk solids in silo forms slope,the bulk solids in the silo in the sloping is separated to two parts,the bulk solids in silo shall form a sloping surface.Under such a state,the bulk solids in the silo can be divided into two parts,one being the upper part of bulk solids with a sloping surface and another being the bulk solids of cylinder with a horizontal surface.Thus the bulk solids in the upper part can be regarded as an imposed load,and according to Janssan′s theory,the bulk solids in the lower part can be analyzed as horizontal and perpendicular pressures.Finally by taking the bulk solids in the upper part as the boundary condition,the expression of the horizontal circumferencial pressure acted on silo wall by bulk solids with its surface being on a sloping state is derived out.
