Asian Simulation Conference/The 6th International conference on system Simulation and Scientific Computing

作者： LI Jingru, ZHONG Denghua (The College of architecture and civil Engineering, Shenzhen University, Shenzhen, 518060, China School of civil Engineering, Tianjin University, Tianjin, 300072, China)

The construction of underground power station is normally one of the most complex construction processes in a hydroelectric project. Discrete system simulation is useful tool for resolving this problem. Despite its widespread successful applications, simulation has not yet been used to its maximum potential due to some deficiencies dampen a project manager's desire to utilize simulation tools. In this paper a Geographic Information System (GIS)-based visual simulation method, in which system simulation techniques are integrated with visualization techniques, is presented to overcome these limitations. The corresponding software, GIS-based Visual Simulation System (GVSS), was developed. GVSS is a powerful planning tool offering visualizing and querying capabilities simultaneously. A real hydraulic and hydroelectric project in China named Nuozadu is systemically investigated using GVSS. The analytical results have been adopted by the Kunming Hydroelectric Investigation Institute of China.

通过铁路桥梁和铁路线路附近的两次现场试验,研究列车对周围地面和邻近建筑物的振动影响。实验结果表明,无论是作为桥墩的点振源,还是作为线路的线振源,铁路附近地面环境和建筑物地板的振动均随列车速度的提高而增大,随距线路的距离增加而减小,但在距线路一定的距离存在着一个振动放大区。对于多层建筑物,较高楼层的振动大,轴重大的列车引起的振动较大;实测铁路附近的楼房地板振动很大,已经超过了我国环境振动控制标准的规定。

作者：陈益民 ZHOU Shuagxi ZHANG Wensheng China Building Materials Academy Beijing 100024 China School of civil Engineering and architecture East China Jiaotong University Nanchang 330013 China

The effects of activated coal gangue on compressive strength, porosity and pore size distribution of hardened cement pastes were investigated. Activated coal gangue with two different kaolin contents, one higher and one lower, were used to partially replace Portland cement at 0%, 10%, and 30% by weight. The water to binder ratio（w/b） of 0.5 was used for all the blended cement paste mixes. Experimental results indicate that the blended cement of activated coal gangue mortar with higher kaolin mineral content has a higher compressive strength than that with lower kaolin mineral content. The porosity and pore size of blended cement mortar were significantly affected by the replacement of activated coal gangue.

关键词： activated coal gangue compressive strength porosity blended cement paste
