heave ratio 中文意思是什麼
heave ratio
解釋
凍脹比-
It was shown that salt expansion value of low liquid - limit clay was accumulated before the sixth freezing and thawing cycles, but the increment of salt expansion was reduced gradually with increasing cycles ; the salt expansion accumulation of low liquid - limit clay could be separated into three phases ; the deformation of clayey sand was mostly frost heave and subsidence under cycles, and collapsibility value of clayey sand was accumulated with increasing cycles ; the variation of salt expansion ratio and collapsibility ratio was a parabolic function of freezing and thawing cycles
試驗結果表明：低液限粘土前五次凍融循環過程中鹽脹具有較好累加性，隨著凍融循環次數的增加，鹽脹量增長速度逐漸降低；含砂低液限粘土的鹽脹過程可以被分為三個階段；粘土質砂在凍融循環過程中的變形主要為凍脹和沉降變形，具有較好的溶陷累加性；低液限粘土、含砂低液限粘土的鹽脹率和粘土質砂的溶陷率與凍融周期之間的關系符合二次拋物線變化規律。 -
The results of experiments show out : the frost - heave stress of normal concrete with low w / c ratio was more small than the frost - heave stress of normal concrete with high w / c ratio under freezing condition
試驗研究表明:受凍條件下，低水灰比基準混凝土凍脹應力要比高水灰比基準混凝土的凍脹應力小。 -
Meanwile, the frost - heave stress of all concrete with different w / c ratio decreased with the adding of mineral additives, the decreaseing extent of concrete with high w / c ratio is more bigger between them
同時，摻入礦物摻合料的不同水灰比混凝土的凍脹應力都減小，其中高水灰比混凝土減小幅度較大。
