摘 要
白潭溝橋，位于鄂陵縣陶城鄉(xiāng)東南部，地貌單元為淮河沖積平原區(qū)，橋位區(qū)周邊地勢平坦，溝谷與橋梁近直交。
水文地質(zhì)條件良好，所跨越河流內(nèi)積水最寬約36m,深約1.5m，河水清澈，水質(zhì)較好，環(huán)境水對(duì)混凝土無侵蝕性。土層無不良地質(zhì)現(xiàn)象，地基土層位穩(wěn)定且分布廣泛，無軟弱土層。本地區(qū)地震設(shè)防烈度為6度，基本地震加速為0.5g，區(qū)域穩(wěn)定性好。
橋梁采用預(yù)應(yīng)力混凝土空心板，并列分離雙幅布置，左、右幅橋等長，上部結(jié)構(gòu)：預(yù)制空心板采用40號(hào)混凝土；現(xiàn)澆鉸縫采用30號(hào)細(xì)骨料混凝土；橋面鋪裝采用30號(hào)瀝青混凝土，欄桿及人行道板采用25號(hào)混凝土?？鐝?8m,橋面凈空為7+2 1.0m，主梁梁高為0.5m，梁長17.96m, 下部結(jié)構(gòu)：蓋梁、墩柱、均采用25號(hào)混凝土；樁基采用20號(hào)混凝土。
在設(shè)計(jì)中需完成的設(shè)計(jì)內(nèi)容：

Abstract
White Lake Ditch Bridge, located in Hubei Lingxian Tao urban and rural south-east, features modules for the Huaihe River Alluvial Plain. Bridge DC surrounding smooth terrain, ravines and bridges nearly orthogonal.
Hydrogeologic conditions are very good, across the river water within the width of 36 m and depth of about 1.5 m, the water is clear and the water quality is better environmental water on the concrete without erosion. Soil no adverse geological phenomena, the foundation soil-stability and widely distributed, and no soft soil. The seismic design intensity of 6 degrees, the basic seismic acceleration of 0.5 g, regional stability.
The proposed bridge using prestressed concrete hollow plate bridge using two parallel separation rate settings, the left and right sites located long, Superstructure : using precast hollow slab of concrete 40; Hinge joints using cast-in-place on the 30th fine aggregate concrete; Deck Paving used on the 30th of asphalt concrete, railings and sidewalks plate used on the 25th of concrete. 18 m span, bridge clearance of 7+2 1.0m, the main high as 0.5m Liang Liang, Liang long 17.96m, Substructure : covered beams, columns, adopted on the 25th concrete; Piles of concrete used on the 20th.
In the design of the required to complete the design content:
(1). the design scheme is selected, the structure arrangement and size drawn up
(2). girders, and the internal force calculation every beam
(3). prestressing tendons estimate and layout
(4). girders section geometry calculation
(5). prestress loss calculation
(6). lasting status stress checking and short stress checking in
