While particular mechanisms of stone decay are intimately linked with the characteristics of construction materials and technics used for a given building as well as the environment of the building (costal constructions for example should support sea water actions while the desert buildings more often a sand loaded wind), some general aspects of stone degradation could be taken into account from a fatigue-like approach.
The data available from similar materials are then used for the parameters S and s ([10]).

Groundwater vulnerability fuzzy evaluation in Qujing basin Xiaoling Zhang1,a, Feng Li1,b, Hongzhan Liu1,2,c 1Faculty of Land Resource Engineering, Kunming University of Science and Technology, China 2 Yunnan Geotechnical Engineering Investigation Design Research Institute, China a 79270107@qq.com , blifeng@kmust.edu.cn, c b.86200613@qq.com Keywords: groundwater vulnerability; DRASTIC method; analytical hierarchy process; multi-layer fuzzy comprehensive evaluation method; Qujing basin Abstract: As the Qujing city’s industrial development, how to use and protect groundwater is the primary problem of urban development because of the non-uniformity distribution of groundwater.
The model was applied to evaluate the groundwater vulnerability of Qujing basin and the east and west sides of the mountain with the consideration of depth to the water table, net recharge, aquifer material, soil type, topography, impact of vadose zone and hydraulic conductivity of aquifer with the help of monitoring data.
