沉降

For settling, the acceleration is obviously due to gravity g.

对于沉降，重力沉降加速度为重力加速度

The traditional smoke theory considers that the smoke particles will sedimentate due to gravity after forming of smoke screen, and then the particles reach a final sedimentation velocity thanks to the effect of air-resistance and buoyancy, and the equation can be solved by the Stokes pellet resistance theory and often used to analyze the performance of smoke.

传统烟幕理论认为，在烟幕形成后，烟幕微粒受到重力的作用开始沉降，同时受到空气阻力和浮力的作用，最后使烟幕微粒达到终端沉降速度，这个速度方程可以通过Stokes圆球阻力理论求得，并被用来分析烟幕的性能。

Settlement characteristics are studied based on formula of suspended sediment settling velocity and previous research results. Results show that the suspended sediment flux quickly decreases from the Hangzhou Bay to the offshore area. Although the suspended sediments are primarily transported towards the offshore area, net transport towards the Hangzhou Bay is also found in the study area. The study area is basically located in hydrodynamic balance belt, and the suspended sediment transport is characteristics of reciprocating movement and small amount of net sediment discharge. The net suspended sediment transport is mainly controlled by average current transport, Stokes drift-induced transport and gravitational circulation transport. The advection transport effect gradually weakens and gravitational circulation transport evidently intensifies from Hangzhou Bay to the offshore area. Settling velocity of single particles is far smaller than that of floccules, so, influence of flocculation of suspended sediments must be taken into the consideration.

结果表明，研究区净悬沙通量自杭州湾内向外海迅速变小，悬沙总体由杭州湾向外海输运，但同时存在向杭州湾方向的净输沙；研究区基本处于水动力平衡带，悬沙输运具有往复搬运、净输沙量小的特点；平均流输运、Stokes漂移输运和垂向净环流输运是引起悬沙泥沙净输运的主要作用机制，自口门至外海，平流输运作用逐渐减弱，垂向净环流输沙在悬沙净输运中所占比例逐渐增加；舟山群岛海域既是杭州湾向东海输运泥沙的重要通道，也是东海沿岸流携带泥沙向南输运的过渡地带；研究区单颗粒泥沙沉降速度很小，远小于絮凝沉降速度，在研究本区悬沙沉降时必须考虑絮凝的影响。

Transport trend and controlling factors of surface sediments are studied by the method of grain size trend analysis.

are gained that after widening, the settlement of two sides of the old road pavement is contrary, cross slope of old road is different, horizontal displacement of the old road pavement is minishes, the area of maxium settlement, maxium lateral displace and disease of old road is different as before widening.

分析结果指出：在拓宽段作用下，靠近老路中心一侧老路路面沉降逐渐减小，远离老路中心一侧沉降逐渐增大，相应横坡也在发生变化；老路路面的水平位移有较大幅度的减小；而且老路最大沉降、最大水平位移、最大剪应力及最易发生病害的位置与拓宽前也发生了较大的变化。
