In recent years the rock-socketed continuous concrete walls have been applied in supporting structure of foundation excavation, and the main problem of which is how to simulate m value of wall bottom bedrock. In this paper, the m value of rock-socketed underground continuous concrete wall bedrock is monitored by a structural test about a typical engineering. The monitored data of foundation excavation supporting deformation are fitted by least-square method, and the bedrock m value of which are researched and analyzed based on an optimization method and fitting deformation curves. The test shows the monitored m value meets the corresponding engineering regulations and is related with the broken degree of rock on the monitored position, and the variability of which is lesser in the construction process.
