The Influence of Environment on the Settlement of Historic Buildings in China

Chinese ancient wooden buildings prefer fronting water and with hills on the back. Therefore, some ancient buildings were built on the bedrock of the mountain. The uneven height of the building platform from the bedrock causes the uneven settlement of the foundation. Due to the disturbance of groundwater, the uneven settlement of the building foundation will also change due to the groundwater. This paper takes the Song Dynasty Jinci Goddess Mother Hall as an example to compare the settlement of the original foundation and the settlement of the repaired foundation. Summarize the effect of groundwater and the bedrock location of the settlement of ancient building platforms under different strengthening methods. The Flac-3D simulation software was used to simulate the foundation and load of the building. The numerical simulation results show that the settlement value after reparation is reduced by 84% compared with that before. The values of the settlement trend are similar to actual data, which has to guide significance for the prediction of building settlement and the protection of the building. Authors can provide references for future protection and the foundation reinforcement of similar buildings by comparing the foundation reinforcement methods by actual measurement and numerical simulation.
