Abstract Aiming at the problems that most of the existing jacking force calculation models are applicable to soft soil and some hard rock strata，which cannot consider the creep effect of soft rock，poor applicability to the soft rock section involved in long-distance rock pipe jacking project，and large calculation errors，etc. Then relying on the Chongqing Guanjingkou Water Conservancy Hub Project，which is the first one that adopts the long-distance rock pipe jacking method for construction，we have developed the following model to solve the problems of soft rock and hard rock，which is the first one in China that adopts long-distance rock pipe jacking method，this paper adopts on-site research and on-site pipe breaking and other methods to explore the deeply buried soft-rock tunnel jacking construction stuck pipe mainly by the soft-rock creep effect leads to the increase in contact pressure between the pipe and rock，which leads to a sharp increase in the resistance of the pipe joints. In this paper，on the basis of indoor creep test of carbonaceous shale，Burgers intrinsic model is introduced，and the viscoelastic displacement solution is obtained by Laplace variation of relevant parameters according to the correspondence principle，and then a theoretical calculation model of time-dependent soft rock contact pressure is obtained according to the principle of common deformation of pipe-rock. Through the tube-rock friction similarity test and combined with the simplified triangular synapse model，the semi-empirical formula of friction coefficient is fitted，and the roof force calculation model considering the creep effect under the soft rock of roof tunnel is obtained. Comparison of the calculated data with the measured data confirms the reasonableness of the theoretical model in predicting the headwall force in soft rock strata.

Key words： rock mechanics pipe jacking jacking force contact friction test soft rock creep
