桥头

Finally, the anchorages absorb some of the force as well.

最后，桥头两座高塔基座也吸收了一部分力量。

The results show that space finite analysis results are close to test ones, bottom chords suffer axial force and large in-plane bending, and the max stress is nearby each middle internode. The max stress of node crossbeams occurs in No.2 bottom flange, and that of internode crossbeams happens in ones lying in the middle of every internode. The concrete slab is in tension at the longitudinal direction, and also suffers bent at vertical loads. The degree of completely-composite model taking part in the combined actions is about 55%, while that of semi-composite model is 42%-43%. The combination of concrete slab and bottom chord increases the degree of floor system taking part in the combined actions, lightens the burden of bottom chord, and reduces out-of-plane bending of node crossbeams especially the ones near bridgehead. Stress and displacement of main truss can be evaluated by a equivalent plane rigid frame in preliminary design, and effective stiffness of bottom chords are composed of original ones and concrete slab, and the concentrated load from deck can be translated into uniform load.

研究结果表明：空间有限元分析结果与试验结果较吻合；下弦杆受到轴向拉力和较大的面内弯矩作用，各节间最大应力出现在节间中点附近；节点横梁最大应力发生在横梁2的下翼缘，节间横梁最大应力发生在位于端节间中部的小横梁上；混凝土板顺桥向整体受拉，并在竖向集中荷载作用下产生弯曲变形；全结合模型大部分节间内的桥面板参与主桁共同作用的程度为55%左右，半结合模型桥面板的参与程度为42%~43%；桥面板与下弦杆结合能够增加桥面板的参与程度，减轻下弦杆荷载，减少节点横梁尤其是靠近桥头横梁的面外弯曲；对桥梁进行初步设计时，主桁杆件的位移与内力可按照1个等效的平面刚架计算，下弦杆的等效刚度由原下弦杆截面和混凝土桥面板截面组合而成，桥面荷载可转化为均布荷载施加。

Any one who had chanced to pass through the little town of Vernon at this epoch, who had happened to walk across that fine monumental bridge, which will soon be succeeded, let us hope, by some hideous iron cable bridge, might have observed, had he dropped his eyes over the parapet, a man about fifty years of age wearing a leather cap, trousers a waistcoat of coarse gray cloth, to which something yellow which had been a red ribbon, was sewn, shod with wooden sabots, tanned by the sun, his face nearly black his hair nearly white, a large scar on his forehead which ran down upon his cheek, bowed, bent, prematurely aged, who walked nearly every day, hoe sickle in hand, in one of those compartments surrounded by walls which abut on the bridge, border the left bank of the Seine like a chain of terraces, charming enclosures full of flowers of which one could say, were they dddtt.com larger:"these are gardens," were they a little smaller:"these are bouquets."

In the past over ten years, many problems, especially soft ground's non-uniform settling and large subsidence after finished and jump-off on bridge's end, arise from highway's building along national construction progresses.

近十几年来，随着国家建设的不断发展，公路建设中产生的问题，尤其是软土地基的不均匀沉降、工后沉降量大、桥头跳车等问题尤为突出，地基处理方法是否选择适当对工程的质量、工期、维修保养以及经济效益均有很重大的影响。

It is caused by the differential settlement between bridge abutment and subgrade. As a result, it badly affects comfort of traveling, reduces velocity of steering, minishes capacity of highway, enhances the damage to vehicles and bridge abutment, and even gives birth to traffic accident.

桥头跳车是由桥台构造物与台背路基之间的不均匀沉降引起的，它的存在严重影响了行车的舒适性，降低了车辆的行驶速度和道路的通行能力，加剧了车辆及桥台构造物的损坏，甚至导致交通事故的发生。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
