MAO Hai-he. Reaction distribution investigation and structural analysis of composite thrust wall of rectangular pipe jacking shaft[J]. 2007, 28(6).DOI:
The thrust wall is a very important component of rectangular shaft; its stress and strain are both fairly complex when it suffered the thrust of pipe jacking. How to make certain the thrust force
which is transmitted from internal lining of working shaft to external soil mass
is quite significant; how much will the soil pre-deformation affect
and these results directly affect the calculation accuracy of retaining structure and internal lining of working shaft. By using numerical modeling analysis method
the thrust force transmission pattern is found; and the reaction distribution in the depth and width direction of the thrust wall is calculated; then the internal forces of each components of the thrust wall are ascertained on the basis of known reaction distribution analysis. This paper offers references for calculating pipe jacking thrust wall according to rational simplification and approximate hypothesis.
