二、高土石坝的原型观测墨西哥的高土石坝一收都埋设大量观测仪器,对施工期和运行期坝体的应力应变进行系统观测,并及时整理和分析资料,以便修改设计和指导施工,从而促进科学研究。埋设观测设备的费用视工程规模而定,一般约占坝体费用的1％(其中包括埋设工人的工资及管理费用)。表3是几个土石坝所埋设的观测仪器及数量。从表可以看出各土石坝
Second, the prototype observation of high earth-rock dam In Mexico, a large number of embankment embankment buried a large number of observation instruments, the construction and operation of the dam of the stress and strain of systematic observation and timely sorting and analysis of information in order to modify the design and guidance of construction, Thus promoting scientific research. The cost of laying observation equipment, depending on the size of the project, typically accounts for about 1% of the cost of the dam (including the wages and management costs of laying the workers). Table 3 is the number of embankment buried in the observation instruments and the number. From the table we can see all the earth and rock dam
