From experimental result, i preliminarily know that eps is good thermal insulation material because the absorption of water is low and heat insulation is good, it is practicable at preserving temperature field of frozen earth roadbed and bringing frozen disaster under control ; second, according to the analysis of the eps that is applied into practical project, i have studied the practical effect which eps preserve roadbed temperature field, and the influence that was made after building field. i have get that eps can influence moisture content and frozen upper limit, through practical measuring data, i have studied freezing and expanding quantity and melting and submerging quantity during a complete frozen and melting cycle as well as have expanded and proved the practical application effect of eps with some reference significance to deep research of some connected problems. finally, through computer data analysis, setting up the analytical model of finite unit, i have simulated the temperature field of roadbed heat preservation, then expounded and proved that the height of embankment influenced the effect of thermal insulation material
其一是對聚苯乙烯泡沫塑料（ eps ）保溫板以及天然路基土層、路堤填料進行了室內試驗分析，結合國內外現在的有關科研成果，綜合確定其各項特徵參數；從試驗結果初步認識到聚苯乙烯泡沫塑料是一種吸水率低，隔熱性好的保溫材料，在凍土路基溫度場的保護和凍害治理方面是可行的；其二通過eps保溫板在現場工程實踐中的應用分析，研究了保溫板在保護路基土層溫度場的實際效果以及修築路堤后造成的影響，保溫板對土體含水量、凍結上限的影響，通過實測資料，研究了在一個完整的凍融周期內整個路基的凍脹量和融沉變形量，論證了保溫板的實際應用效果，對有關問題的進一步研究和相關工程設計具有參考意義；其三，通過計算機數值分析，建立有限元分析模型，對保溫路基的溫度場進行了模擬計算，論證了路堤高度對保溫材料效果的影響。 -
Dynamic control of the limit water level belongs to non - structural measures of reservoir operation. with the analysis of the cause and rule of flood in the catchments and taking advantage of hydrology and metrology information, the operable method can be obtained which not only satisfies the flood prevention but also takes full advantage of flood resources, and the upper and lower limits of the limit water level are determined with serial hydrology calculation. then, the rule of using the upper and lower limits is put forward to reach a beneficial flood operation with small risk
汛限水位動態控制方法屬於水庫風險調度的非工程措施范疇，通過分析流域洪水的成因和庫區降雨及致洪規律，結合水庫的蓄泄能力，積極慎重的利用水文氣象預報信息，研究既能滿足防洪要求，又可充分利用洪水資源的可操作性的調度方法，利用水文系列的連續演算方式推求汛限水位的變化范圍，提出使用汛限水位上下限的原則，達到風險較小、效益較大的目的。 -
The results indicate that while variable dampers significantly reduce the response as compared to the case with no control, no reduction or the worse situation is observed when compared to the same device acting as a passive damper with the upper limit of the damping of the corresponding variable damper
在大多數情況下，粘性變阻尼控制與無控相比可以顯著減小結構的動力反應，但與相應的被動上限阻尼控制相比並不能進一步改善控制效果，甚至有所不及。
