Gezhouba analysis of river flow conditions upstream and downstream channel

Around 0o_21. Between the Li River as the water volume to reach river reaches the bridge, the mainstream flow direction of the center line of the basic flow and channel overlap, so there is no transverse flow of the paragraph. 2.3.1 Wave flow 2.3 in 1993, has carried out Gezhouba river channel downstream of the wave observations, due to limited observation equipment, when the first four Wuxi Rong, et al: Gezhouba river channel upstream and downstream flow conditions of '91 'when not given the observed data, field tests reflect real ship within the river channel downstream of the larger waves, flow pattern is also more disordered. May 2006, Gezhouba river downstream river channel outside the left edge separation levee construction is completed, the existence of the river dike, blocking the downstream Gezhouba power station tailrace river river channel a lock on the gate under the first river to Beacon Hill the role of the waves of the Channel and the river water within the embankment construction than before, with the traffic situation has obvious visual wave decreases, due to lack of appropriate measuring instruments, also no measured data, July 2007 8 (8:00 the day flow 33700m3 / s) observed the middle of the river embankment section of water under the dike nose above the wave peaks and valleys about 0.2IIl ~ 0.3m. For the middle of the river dike construction blocking the river, the Second River water into the Beacon Hill power station generating a roll of the end of the bridge is not the role of river reaches, within the scope of that section of flow channel still Gezhouba power station and river discharge for such factors as the boundary impact and constraints, therefore,[link widoczny dla zalogowanych], inspected the section of the flow pattern within the channel is still poor, the wave is still large, July 8,[link widoczny dla zalogowanych], 2007 (the date of 8:00 traffic 33700ms) observed the flow of the paragraph about the wave peaks and valleys To 0.4m0.6m. 2.3.2 Diagonal middle of the river before the embankment construction, due to major power plants, power plants and other power end of the Second River flows tend to river water flow path, therefore, Baida Jiang navigation separation levee downstream end of the beginning of the downstream river channel within the whole, are there flow sizes, varying the direction of oblique water flow, mixed flow with the discharge for the size of the size of the changes. Middle of the river embankment construction, the river downstream of the first * 1 lock gates of a river embankment under the under the Dyke River,[link widoczny dla zalogowanych], blocking the river dike,[link widoczny dla zalogowanych], river power stations so that most of the end of the water barrier in the channel outside the fairway on the right most of the water back to the slow flow in the waters of the basic,[link widoczny dla zalogowanych], relative to channel center line and ship navigation route, the basic flow is not diagonal, the design channel near the river channel near the left part of the water line, there is relatively less inclined water flow. Beacon Hill middle of the river embankment of a river under the Dyke, the river channel at the corners, two major power stations and power station tailrace river washed into the river channel top of range, form a strong diagonal flow, and flow velocity is relatively large; Beacon Hill for a Bridge Creek river volume, flow direction and the channel center line of basic smooth, unlike the little stream channel center line of the diagonal, the horizontal velocity is also very small. 3 Conclusions 1) Downstream Channel Gezhouba river flow velocity within the power station with the increase of discharge for, but in different sites and times, and its rate of increase are different. 2) The middle of the river embankment project construction, and mitigation for the barrier into the next major power station tailrace Beacon Hill navigation above the wall of a river channel waters, reducing the flow velocity, and expand back, slow flow waters, has an important role. Flow velocity with the flow rate in the middle of the river dike built after the construction of more ago, in the next section of river downstream of the navigation channel on the waters between the wall of a Beacon Hill reduced to a certain extent, these reach the lower Beacon Hill is still the same as before with the original construction. 3) Dyke river downstream of a river embankment under the scope of Beacon Hill Reach the largest river flow horizontal flow, when the flow is 33000m3 / s, its center line angle and channel water to reach the mainstream of 51o, the corresponding value of the maximum horizontal flow velocity up to 1.07m / s. 4) After the construction of river embankment works, under the guidance wall Gezhouba river downstream of a river embankment between the paths under the dike nose, according to visual observations and field, extended back, before the construction of the flow pattern over a certain degree of improvement But the middle of the river embankment under the following paths Dyke, the flow pattern did not change significantly.
