To calculate the temperature along double pipelines laid in one ditch easily and accurately, soil temperature field and the temperature along pipelines were studied with analytic caluculation method. A model of soil temperature field around pipelines was established. Conformal mapping method was applied to dispose the model.Analytical expresions of soil temperature field along the radial direction and temperature along the pipeline were drevied. Under certain conditions,the expressions were used to proceed calculation. The result shows that the maximum error is merely 0. 58 ℃ ,showing that the analytical soultion is accurate enough to be used.
