Abstract:Through analysis on influence of comprehensive outpatient health[CD*2]care building construciton of Qilu Hospital of Shandong University, it is regarded that Quaternary fragemental pore water and fissured fracture of Ordovician karst water are two different water systems.The proposed construction has not exposed in the excavation depth of the Quaternary within the conglomerate layer. It remains part of the conglomerate as the base layers, and maintains the underlying natural clay water tight performance. It will not stop the groundwater runoff recharge channels, and will not influence the springs.
