1Analysis of surface subsidence rule of the shallow subway tunnel construction WANG Feifei1, a, BAI Huiren1, b, LI Jingjing1, c 1 Dalian University Civil Engineering College Dalian Liaoning 116600 China awangfeifei2005@126.com,bbhr60@163.com, c leigongshan1@126.com Corresponding Author: BAI Huiren,professor,email:bhr60@163.com.
So it has important significance to study about the ground settlement of Dalian Metro section 202. 1 Engineering background Dalian subway 202 section (Cujin Road station-Chunguang Street station) design range for mileage DK11 + 365.945 ~ DK12 + 013.350, the interval landform denudation for low hills, ground elevation is 7.69～22.78 m.
Table 1 Winkler model settlement data and 04 section measured data Field test results and the ground surface settlement calculation model winkle are identical with each other, winkler calculated value is smaller than the actual observations, only practical writing Kerr surface subsidence prediction model can draw the trend of surface subsidence, it can't accurately draw maximum settlement. this is because the soil above the tunnel in the actual engineering fill is the artificial hormone and have a small amount of construction waste, theory and assumes that there is a certain gap; At the same time in the theoretical calculation without considering bellows-liquid coupling condition soils and the distortion of the structure is in compliance with linear elastic properties.

The Surface Characteristics of Exterior Wall External Insulation System with Foamed Glass in Weathering Resistance Test Xiaoyan Wua, Yiying Luob College of civil engineering and architecture, Jiaxing University, Jiaxing, Zhejiang, 314001, China awxymumu@163.com, bluoyiying66@163.com Keywords: foamed glass; exterior wall external insulation system; weathering resistance; Surface characteristics Abstract.
However, the external thermal insulation engineering will suffer from great thermal stress during its actual use.
So the weathering resistance test has good relevance with the actual engineering.
