Fruticosa grown in clay sandy soil and clay soil was best, and they were significantly higher than that in other soils from 12th d in the test. The biomass of hypocotyls in 4 soils was similar, and that in forest soil was higher and its dry weight accumulated in hillside soil was more.

沙土和黏土中紫穗槐根的生物量最好，并在第12天的时候开始就明显高于其他土壤。4种土壤中的下胚轴生物量都差不多，以森林土的较高，而山坡土的积累的干重较多。

Comparison with grain size measured under proper conditions using traditional methods shows that the lase...

将合适条件下测得的软土粒度分布与传统方法得到的结果进行了对比分析，结果表明，激光粒度仪测量的粒径分布范围较广，采集的数据点比传统方法要密，测量的精度要高于传统方法，因此可以用激光法代替传统方法，以快速准确地测得软土的粒度分布。

3D effect is analyzed and the average velocity of wave propagating in the pile, which mainly influences inverse interpretation, is discussed. Finally, the theory results are verified by model experiment. It is shown that 3D results have the same phase with ID results. The pile radius, the duration of impulse, the ratio of hammer radius to pile radius and shear velocity of the soil around the pile have influences on 3D effect. The best position of receiver is 0.55R from the pile center. The average velocity of wave propagating in the pile reduces due to transversal inertia effect and 3D effect.

结果表明：三维曲线与一维结果在相位特征上一致；波场图直观地反映了波在桩中的传播规律；三维效应与桩径、激振脉冲宽度、相对激振半径及桩周土剪切波速有关；传感器放在0.55R处可以得到干扰较小的信号；三维效应和横向惯性效应的存在会使桩中的波速减小，土的性质对波速影响不大；反演精度与缺陷的性质、激振条件有关。
