中文摘要:
      近年来,随着地下空间利用的不断扩展,地下水抗浮问题日益突出。因地下水位变动而引起的工程事故也屡见不鲜。经过多年观测研究,对比搜集大量水文地质、气象等资料,采用数值法、动态曲线比拟法、水量均衡法等多种方法对西宁地区抗浮设防水位进行了科学、合理的分析研究,得出总的规律是:河漫滩和一级阶地抗浮水位变幅可达3~4 m,二级阶地一般在1.5~2 m左右,三级阶地则在0.5~1.5 m之间。这一结果和原先青海省统一认可和普遍使用的0.5~1 m水位变幅差距较大。也可以就此找到近年来西宁建(构)筑物抗浮事故频发的根源,从而引起人们重视。对西宁地区的抗浮设防水位取值问题有可靠的指导意义。同时,对其它地区抗浮水位取值也具有一定的参考价值。
英文摘要:
      In recent years, with the expansion of underground space utilization, the anti-floating problem of groundwater becomes more and more prominent. Engineering accidents caused by fluctuation of underground water level are also common. After many years of observation and research, a large amount of hydrogeological, meteorological and other data were collected by comparison, and a variety of methods including numerical method, The general rule is that the anti-floating water level of floodplains and first-class terraces can vary by 3-4 M, the secondary terraces are generally about 1.5-2 M, and the tertiary terraces are between 0.5-1 .5 M. This result is quite different from the 0.5-1m water level variation that was originally recognized and commonly used in Qinghai Province[7] And ... It is also possible to find the root cause of frequent floating accidents in Xining building(structure) in recent years, which has attracted people’s attention. dynamic curve analogy method and water balance method were used to conduct scientific and reasonable analysis and research on the anti-floating fortification water level in xining area. At the same time, the value of anti - floating water level in other areas also has some inspiration.
