Abstract: By using stochastic theory, settlements of ground surface over a extra-shallow-underground-pipe jacking with curve in Drainage Engineering in the down town area of Chongqing City are analyzed, and the simplified calculate formulas are deduced. Comparison between calculated and measured settlements shows that they are relatively approximate. So it is demonstrated that stochastic medium theory is applicable for actual engineering.

Key words: extra-shallow-underground-pipe jacking, ground settlement, stochastic medium theory

摘要： 应用随机介质理论对重庆主城排水超浅层曲线顶管顶进过程的地表沉降进行了分析,并推导出简化的沉降计算公式,进行了理论计算沉降与实测沉降对比,对比结果证明该理论在一定条件下也适用于超浅层顶管引起的地表沉降.
