Self - balanced testing method has advantages over conventional testing method in safety , economy and high load capacity 自平衡試樁法具有經(jīng)濟性、安全性、高荷載能力等優(yōu)點。
Based on above three methods of transferring self - balanced test data into top load data have been provided and relative computer program has been edited 結合本文的研究成果,在實際工程中進行了自平衡試樁法與靜載試驗的對比試驗。
Self - balanced testing method was performed to several piles of three bridges and the conventional anchored pile method to another respectively 其中三座大橋的樁基試驗采用了自平衡試樁法,另一座大橋的樁基試驗采用的是傳統(tǒng)的錨樁? ?反力梁體系。
Since the work condition of real piles is different from that of testing piles as well as the complicity of mutual effecting between soil and pile , the position of o - cell is indefinite , leads to inaccurate results . author developed some ideas to improve self - balanced testing method 自平衡法與樁的實際工作條件不符,由于樁土體系的復雜性,導致荷載箱位置的不確定性,而荷載箱位置的變化,將會得出不同的試驗結果。
What ’ s more , it is effective way to study the negative friction , the side friction of pile - soil , because its o - cell can be placed any part of the pile . but self - balanced testing method is incapable of acquiring the conventional load - settlement curve , q - s curve , several transformation method have been developed 但是,自平衡試樁法不能直接得出傳統(tǒng)的荷載? ?沉降關系,由此方法得到的兩條q ~ s曲線,必須將其轉換為傳統(tǒng)加載的q ~ s曲線后才能分析試樁的沉降量。
