... or foundation. But re-assessing the current safety of an existing dam is many times more difficult than ensuring that a dam-to-be-built satisfies all safety criteria. In sliding stability re-assessment of concrete dams, sliding along potential weakness planes in the rock foundation is an important...

... difference of photovoltaic support is 0.008 times of support purlins span. Thirdly, when the sum of overburden fracture zone height and load influence depth are less than buried depth of goafs, the foundation of coal sinkhole region is in a stable state and it cannot cause ground subsidence, so the coal...
