Abstract: Based on "Elastic Bending Resistance", the article applies the weighted remainder method to approximate analysis and calcultion of buried pipeline load at rising temperature so as to simplify the analysing and reasoning process, derives the analytic expression for plane bending of horrizontal "L" buried pipeline shown by a multinomial, and gives out the equation for calculation of the load at rising temperature. Applying the method mentioned above, it is only by working out a short BASIC programme and taking very lictle operating time that the values snch as bending, cross section corner, bending torque, shearing stress, axle stress can be calculated at any point on a pipeline and thus find out the distribution of each value on the anchor. In comparison with the calculation resulls in Literatures (1) and (2), the results obtained in this article is resonable with enough engineering accuracy.
