Excavations in Unstable Rock Mass
This chapter begins by providing some general recommendations for excavation in unstable rock mass. Then, it discusses magnitude of rock mass pressure. Generally, determination of the rock pressure is based on the existing joints. As the magnitude and distribution of the rock mass pressure are a function of the rock mass disturbance level, concrete rules such as for the determination of earth pressure distribution in soil cannot be specified. The load approach for the rock pressure shall be selected conservatively based on the respectively determined local conditions. The chapter ends by discussing the bearing capacity of rock mass for support forces at the embedment depth.
