摘要
本文根据新安江大坝二十多年的温度和应变实测资料,对大坝的温度分布和温度场、无应力变形、坝体应力、坝踵及坝基应力等进行了分析.指出了坝面湿胀应力的存在,提出了基岩应变计湿胀应力的估算方法,对内部观测仪器在大坝安全监测中的作用给予了有力的论证.
On the basis of measured data of temperature and strain in Xin'anjiang dam ftor more then twenty years, the temperature distribution, and temperature field, he non-stress deformation, the stress in the dam body, the stress at the heel and toe of the dam are analyzed. The existence of moisture swelling on the upstream dam face is pointed out. A method of evaluation of the moisture swelling stress from the foundation extensometer is presented. An effective, demonstration and proof have been given of the fuctions of internal observation instruments in dam safety monitoring.
