車輛載重試驗結果顯示，輕質跨具有相對較低的斷面剛度，結構勁度約在常重跨

車輛載重試驗結果顯示，輕質跨具有相對較低的斷面剛度，結構勁度約在常重跨之75~80%左右。預力箱梁結構遠距微波動態分析結果顯示，輕質粒料混凝土大幅降低結構體質量後，其降低之慣性已經彌補剛度較低之差異，在混凝土灌漿預力施拉一年後，其整體之第一模態振頻已經與常重跨相當。以上試驗結果證明在相同的環境條件下，是可以使用水庫淤泥輕質粒料混凝土取代一般之常重混凝土製作預力混凝土。

結果 (英文) 1:

Vehicle load test results show that lightweight spans have relatively low section stiffness, and the structural stiffness is about 75 to 80% of normal-weight spans. The long-distance microwave dynamic analysis results of the prestressed box girder structure show that after the lightweight aggregate concrete significantly reduces the mass of the structure, its reduced inertia has made up for the difference in lower stiffness. After one year of concrete grouting prestressing, the overall The first mode vibration frequency is already equivalent to the constant weight span. The above test results prove that under the same environmental conditions, reservoir silt lightweight aggregate concrete can be used to replace ordinary normal heavy concrete to make prestressed concrete.

結果 (英文) 2:

The vehicle load test results show that the lightweight span has a relatively low cross-sectional stiffness, with a structural stiffness of about 75-80% of the normal weight span. The results of the remote microwave dynamic analysis of the prestressed box girder structure show that the inertia of the reduced lightweight aggregate concrete has made up for the difference of the lower stiffness after the mass of the structure is greatly reduced. One year after the concrete grouting preload is applied, the first mode frequency of the whole structure has been equivalent to the constant weight span.
The above experimental results prove that under the same environmental conditions, reservoir silt lightweight aggregate concrete can be used to replace ordinary heavy concrete to produce prestressed concrete.

結果 (英文) 3:

The vehicle load test results show that the light span has relatively low section stiffness, and the structural stiffness is about 75~80% of the constant weight span. The results of remote microwave dynamic analysis of prestressed box girder structure show that the inertia of lightweight granular concrete has made up for the difference of lower stiffness after greatly reducing the weight of the structure, and the first modal vibration frequency of the whole structure has been equivalent to that of a constant weight span after one year of prestressed concrete grouting.
The above test results prove that under the same environmental conditions, reservoir silt lightweight aggregate concrete can be used instead of ordinary heavy concrete to make prestressed concrete.
