Strain detection method for raft foundation mass concrete
The invention discloses a raft foundation mass concrete strain detection method, and belongs to the technical field of mass concrete strain calculation. The strain detection method comprises the following steps: acquiring the length, width and thickness of a raft and the width of an expansion reinforcing band; according to the length, width and thickness parameters of the raft and the width parameter of the expansion reinforcing band, the length-to-width ratio A of the raft, the length-to-thickness ratio L of the raft and the width ratio r of the raft to the expansion reinforcing band are obtained through calculation; determining the expansion rate e of the expansion reinforcing band; and constructing a formula model between the 60d strain epsilon of the maximum strain point on the surface of the mass concrete of the raft foundation and the A, L, r and e, and calculating according to the formula model: epsilon = 1.34674 * 10 <-4 > + 4.5527 * 10 <-6 > A + 1.01664 * 10 <-6 > L + 3.01561 * 10 <-6 > r-0.0949 e to obtain the 60d strain of the maximum strain point on the surface of the mass concrete of the raft foundation. According to the formula model disclosed by the invention, the strain of the maximum strain point 60d on the surface of the mass concrete of the raft can be simply and accurately calculated.
