中文拼音 [bàsǎ]
壩灑
英文
ba xat-
This paper establishes a model simulating dam actual placing process and considering the non - continuity of initial temperature on the boundary of new and old concrete, daily air temperature change, concrete - placing temperature, hydration heat, heat insulation on boundary, water - storing process, placing intermission and curing with water. the calculation of stress field considers the concrete weight, static water pressure, thermal stress, different autogenous volume change between rcc and normal concrete, change of elastic modulus of concrete with age and creep action
考慮了乞今最為全面的初始條件和邊界條件，包括模擬壩體的實際升程過程，考慮了新老混凝土接觸面上的初始溫度不連續，逐日的氣溫變化，混凝土的入倉溫度，水化熱溫升，邊界保溫，水庫蓄水過程，澆築間歇以及灑水養生等因素；應力場的計算考慮了混凝土的自重，靜水壓力，溫度應力，常態混凝土與碾壓混凝土不同的自生體積變形，混凝土的彈性模量隨齡期的變化以及徐變的作用。According to plentiful of experimentation, some new build techniques are created, for example the technique of no watering fill in winter, the technique of prevent frostbite and crack of faceplate etc. these techniques were proved by the project of lianhua cfrd. at last this paper gives some conclusion
而且根據地區特點，進行了大量的實驗，給出了以往一般面板壩所未遇到過的施工工藝，如冬季堆石體不灑水填築、面板的防凍抗裂、壩體渡汛措施等以及採用新的爆破方法開採石料等新的施工工藝。
