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。

The west dam faced the inner sea of rocky harbour and was 2, 470 ft. long and 333 ft. high. the construction of the 2 dams was a complicated process, as 2 cofferdams had to be constructed at each of the sites, before the main dams could be built. these were to keep the dam sites dry for construction
兩條主壩建築工程相當復雜,在興建主壩之前,需于建築
堤壩地點建造圍堰,將海水
隔開,抽乾海床范圍內的海水,挖除黏土和沙,才築
堤壩,使主壩能穩固地建造在堅硬的巖石上。
A formula of n = can be used to calculate the residual salt marsh area outside the seawall when reclaiming, in which m means the new reclaiming area of the salt marsh, p means the prograding rate of the salt marsh, n means the ecology recovering period which is equal to the interval between two reclaiming along the same coast
可以通過式子計算新圍海
堤外側需要予留的鹽沼面積。式中, m為新圍面積, p為鹽沼增長速度, n為生態恢復周期(等於同一岸段兩次匡圍的時間間
