Construction And Temperature Controlling Simulation Analysis For Wanjiakouzi RCC Arch Dam

With the construction of ShiMenzi ZhaoLaihe ShaPai and DaHuashui 100m level RCC arch dams and the 167.5 m high WanJiakouzi RCC arch Dam, more and more development of CRC is gone deeply, and concerned research productions achieve the level of world. Simulation analysis of mass concrete structure is powerful tool of the research for RCC dam .We analyse the temperature field and creep stress field of dam which is concerned with time process by means of Finite Element via simulating temperature controlling measurements, such as construction process, joints design, concrete cooling and so on. Further more, it also can supply consultation for design, construction and temperature controlling measurements of RCC dam.GXED entrusted the geological model test research of WanJiakouzi to Professor ZhangZhongqing. Based on Simulation analysis algorithm of our lab, the research of this paper is Simulating and analysing the temperature and stress for the modified design of WanJiakouzi RCC dam in period of construction. Based on the flat of ANSYS, we have done the works below: 1. Summarize the Simulation analysis algorithm and the concerned research production of our lab which is under the lead of Professor Zhang. Based on the theory of equivalent difference in temperature simulating the volume distortion of concrete structure, a method which is making use of equivalent quantity of heat to simulate and analyse great structure finite element model is proposed in this paper. The proper programme of WanJiakouzi RCC Arch Dam Project also can simulate and analyse the delay expanded property of MgO concrete.2. Simulation analysis for WanJiakouzi RCC Arch Dam with no transverse joint is processed which was added 10m high. Compared with the temperature field and creep stress field production of 157.6m dam, we construe simulation analysis production and design the dam joint disposal and temperature controlling measurements.3. The design of dam joint disposal as 2 transverse joints and 4 induced joints is put forward and other temperature controlling measurements are managed. The programming of WanJiakouzi RCC Arch Dam Project is applied to simulating and analysing the temperature field and creep stress field. The feasibility of joint disposal is demonstrated based on the very production.4. Based on the productions considering the autogenous volume deformation and temperature controlling measurements, appraise the effect which due to the adoption of temperature controlling measurements for the dam. At last, we advised the proper temperature controlling measurements for WanJiakouzi RCC Arch Dam Project.
