风雨操场综合楼改造工程设计与施工

某风雨操场综合楼改造工程拆除了辅助用房及支撑网架屋面的西根框架柱改造成为球场看台。设计采用钢结构桁架托换技术，将屋面荷载转移至两侧的保留柱上，跨度拓展到30m。钢桁架与框架柱上安装的牛腿铰接连接，通过牛腿背面框架柱间的混凝土墙平衡牛腿传来的弯矩。在施工安装过程中合理地利用待拆除框架柱，保持屋面的完整性提升屋面，达到了对屋面扰动影响最小的目的。

充油型脱醇型硅酮密封胶性能研究

研究了甲基硅油、低分子量聚丁烯、氢化烷烃油作为增塑剂用于脱醇型RTV-1硅酮胶对其性能的影响。结果表明:甲基硅油增塑剂对降低模量、提高位移能力效果明显;聚丁烯与聚硅氧烷相容性差,影响与基材的界面粘接;少量添加烷烃油能起到与甲基硅油类似的效果,但热失重超过10%,添加量增加对基材的粘结性变差,其它性能也大幅降低。     

Movement characteristics of Karst water in a deep mining area

In order to study the movement characteristics of groundwater in a deep mining area and solve the dispute of the distri-bution rule of hydro-chemical zoning which is contradicted by lixiviation water zoning in a horizontal direction, we directed our attention to the source of deep groundwater, its seepage and hydro-chemical characteristics in a typical mining area. We used a neotectonic water-control theory, chemical and isotope methods, as well as a method for analyzing dynamic groundwater conditions. The results indicate that 1) Karst water in the deep and medium parts of this mining area is recharged by vertical leakage through neotectonic fractures rather than seepage along strata from subcrop parts or surrounding flows; 2) from surface to deep leakage paths, the variation in the types of chemical groundwater agrees with the normal lixiviation water distribution rule and the age of mixed groundwater increases; 3) the water-rich zones along neotectonic fractures correspond with water-diluted zones in a hori-zontal direction; 4) the leakage coefficient and water capacity of aquifers increases during the flow process of Kant water along the antidip direction (from west to east) and 5) Karst water in shallow mining areas forms a strong runoff belt along strikes and quickly dilutes the water from deep and medium mining areas. Overall, chemical and dynamic water characteristics actually agree with in terms of the entire consideration for differences in vertical leakage and abnormalities in the zone of water chemical distribution, along a horizontal runoff direction.
