| 摘 要： | 深基坑工程的坑底隆起稳定性受多种随机性与模糊性因素影响．将模糊概率和可靠度分析法结合起来，引入了深基坑隆起破坏分析的普朗特尔公式，通过实例分析，计算了深基坑隆起失稳的模糊破坏概率和模糊可靠度．结果说明，模糊随机方法能够合理地反映基坑的实际稳定性．

| Abstract: | The heave stability of deep foudation pit is effected by a number of random and fuzzy factors. Combining fuzzy probability and reliability analysis,introducing the Prandtl formula on bulge fracture analysis of deep foundation pit,fuzzy failure probability and fuzzy reliability is calculated by means of a project example on the heave instability of deep foundation pit. The results showed that fuzzy-random analysis can reasonably reflect the actual stability of foundation fit. |
