【摘要】 从收集到的２９５组，五家地质勘察院所做的万县市区土工实验资料，试图找出土体各参数的分布以及相关关系，并仅用于可靠度法分析边坡的稳定．边坡安全程度的算例说明，用确定性方法计算是稳定的边坡也可能失稳，可靠度的计算方法能更客观的反应出边坡的安全程度．更多还原

【Abstract】 The paper presents probability analysis of earth characteristics in territory of the Three Gorges Project with the help of 295 group data and shows that β distributinon of c and  may be more appreciated than the Normal Distribution.The example indicates that the stable earth slop determined by specified soil properties is an unstable with the aim of reliability theory.Due to the Three Gorges project smooth development,there is a need to collect more soil mechanics data to achieve assessment of soil properties and their distribution so as to assure earth slop stable for resident relocation,building,harbor and highway reconstruction.更多还原
