Based on the simulation model theory of temperature and stress fields presented in this article, a large simulating program for high rccd has been developed, which can numerically simulate all kinds of temperature control measures, including water pipe cooling, heat insulating in winter, reducing place temperature of concrete, spraying water brume, and long interval over - watering surfaces overflowing in flood season.
基於本文提出的溫度場和徐變應力場模擬模型理論，編制了高碾壓混凝土壩的三維有限元模擬計算程序，在程序中考慮了各種溫控措施的數值模擬，包括：水管冷卻、冬季保溫、降低混凝土的澆築溫度、夏季混凝土表面噴水霧、施工汛期壩頂面過水等。 -
When catchment area, average channel gradient and catchment shape factor of designed culvert or bridge are known, a user can be convenient to get local parameters c, e and b from standard contour charts and easy to calculate flood flow just by a calculator. design period of flood flow is enormously shortened as well as a high precision. estimated flood flow through culvert or small bridge by new calculation model is generally less than by traditional methods, so that much cost is cut down a s reducing the span of culvert or small bridge
以75000km ~ 2的川中丘陵地區為試點研究區，繪制了該地區新模型的參數等值線圖，率定了不同設計頻率的改正系數，使設計者只需在地形圖上獲取集水面積，河道平均坡降和流域形狀系數，在參數等值線圖上查得橋涵所在地的相應參數，使用計算器即可迅速計算出設計流量，大大縮短了設計周期，且精度較高，設計的洪水流量一般低於傳統方法，從而可減小橋涵跨徑，節省投資。 -
The comprehensive control of soil and water loess makes the seasonal distribution of river flow more even by reducing more in flooding season and less in non - flooding season. the paper proposed a method to analyze the impact of the integrated control of soil and water loess on flood flow in a large - scale catchment
水土流失綜合治理使汛期徑流量減少程度大，非汛期減少程度小，從而使枯季徑流量占年徑流量的比例增加，汛期徑流量的比例降低，徑流量的季節分配趨于均勻。 -
The reasonable limited water level can solve the conflict between flood control and profit during flood period of complicated hydraulic engineering system, and the aim of reducing flood disaster loss and getting maximum system profit can be realized
合理的汛限水位可以更好地解決復雜水利系統汛期防洪與興利的矛盾，進而達到減少洪災損失、發揮系統最大效益的目的。 -
With the rapid development of satellite remote sensing technology, it has been widely applied in national economics and martial area, in particular, in the field of natural disaster reduction, for examples, in forecasting and controlling of flood, preventing of forest - fire, monitoring of landslide and debris flow and so on. regretfully, as we understand the satellite remote sensing technology are rarely applied both at home and abroad for earthquake disaster reduction. it is because that on the one side, earthquake is a very complicated natural phenomenon with its indistinct genesis mechanism and occurrence of very low probability and on the other side, the resolution of satellite remote sensing image is too low and satellite repeat period is too long that constrain this technique to be used in earthquake disaster reduction. this paper intends to address the application, practicability and other relative scientific - technical and economic issues, of satellite remote sensing technology in reducing earthquake disaster, it is believed that the earlier use of satellite remote sensing technology in china will provide a more effective and economic vehicle to minimize the future earthquake losses and also successful experiences to the world communities
衛星遙感技術在減輕自然災害中發揮了十分重要的作用，但也不得不指出，衛星遙感技術在防震減災工作中，無論在國內或國外均尚未得到有效的應用.這一方面固然是由於地震事件十分復雜，地震孕育和發生的規律尚未搞清，難以發揮衛星遙感技術的作用，另一方面也由於可以使用的衛星遙感技術的解析度還不夠高，重復觀察的周期長，限制了這一技術在防震減災工作中的應用.有鑒于近年來衛星遙感技術有了新的進展，使其有可能在防震減災中發揮特殊的作用，本文旨在對衛星遙感技術在防震減災工作的應用，對它的可行性、有效性、經濟性和與此相關的科學技術問題進行探討，使這項技術能在防震減災領域早日得到應用，以促進我國防震減災工作的發展
