【摘要】 通过地质工程勘察和资料收集,充分掌握了大水沟场区斜坡的地质条件、结构特征及变形机制后,将该斜坡划为2个分区。利用传递系数法,I区选取1-1、2-2、3-3 3个剖面,II区选取4-4、5-5、6-6 3个剖面,分别计算在天然和天然+暴雨(1/3饱和)2种工况下的稳定系数,分析其稳定性,得出结论:I区只有3-3剖面在储料罐附加荷载长期作用和暴雨条件下存在滑动可能;II区坡体前端浅表层处于不稳定状态。更多还原

【Abstract】 Through geological engineering investigation and data collection,we have fully grasped the geological conditions,structural features and deformation mechanism of the slope in Dashuigou area.The slope is divided into two partitions.Using the transfer coefficient method,three sections of 1-1,2-2,and 3-3 are selected in area I,sections 4-4,5-5,and 6-6 are selected in area II.The stability coefficients of two natural and natural rainstorms(1/3 saturated) are calculated respectively,and their stability is analyzed.Come to conclusion:the 3-3section may slip under the long-term action of the additional load of storage tank and under the condition of rainstorm;the shallow surface is stable at the front of the slope.更多还原
