Experimental Study on Dynamic Behaviors of Concrete Bridge in China Existing Railway Speed Increase to 200~250km/h Penghui Liu1, Yiqian Yang1, Jingchuan Yao1, Wei Wang1, Zhensheng Dong1 Railway Engineering Research Institute, China Academy of Railway Science, 100081 Beijing, China email: liupenghui@rails.com.cn, yangyiqian@rails.com.cn, yjcwxj@rails.com.cn, wangyawei5241@126.com, dzhsheng007@163.com KEY WORDS: Bridge; Dynamic Behaviors; Speed Increase.
Because of the low speed early, which of the passenger train is less than 120km/h and the freight train is not ruled in design code with the operating speed of 60km/h, the bridge were designed to fulfill the requirement of ultimate capacity and save material.

The Prediction for Favorable Areas of Hot Dry Rock Exploration in the Northern Part of Songliao Basin Xiaoxiong Wu1, a, Shangming Shi1, a, Pan Zhao1, a, Huabin Wei1 a, Liang Zhang1, a and Xuemin Bai1, a 1Northeast Petroleum University, Earth Sciences, Heilongjiang, Daqing.163318, China; a xiaoxiong_wu@163.com Keywords: Songliao Basin, geothermal resources, Hot Dry Rock, geothermal gradient abnormal Abstract: After years of research about the geothermal resources in the northern part of Songliao Basin, preliminary results have been achieved in the exploration and development of middle-shallow layer geothermal resources and oilfield production water geothermal resources.
Meanwhile, the deep fracture deeply cut earth crust, become weak belt, and become the rising channel of mantle material and the heat flow, create good conditions for the base hack, intrusion, convection of magma and formation of Hot Dry Rock, while the deep fracture controls volcanic activity of the basin and the basin basement, and make up the fracture net connected the upper mantle heat source together with fracture in basin.

The flywheel workload can be increased using fiber-reinforced material, which increases the energy density.
Maximum rotational speed with objectives to achieve high utilization without exceeding maximum material stress determines the required moment of inertia and hence its geometry.
The ecological assessment considers the overall material and energy flows and additional environmental pollution over the product life cycle.
