As compared with the traditional irrigation-traditional fertilization, the following results of the improved traditional irrigation-optimized fertilization were obtained: reduced tiller number per unit area, lower percentage of the tiller ear number/the tiller number, the decreased ear number per unit area, the greatly reduced grain number per ear (1999-2000) and like weight of 1, 000 grains; almost the same plant height; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; lower LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; shorter and thicker flag leaf, 2〓 leaf, 3〓 leaf and 4〓 leaf from top, reduced total area of these leave; bigger mean canopy leaf tilt angle, smaller light extinction coefficient , higher ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and tighter plant type; almost identical dynamic change of flag leaf chlorophyll content; and almost the same root amount in 0-120cm soil layer, smaller rate of progressive decrease of the root length density and root weight density with soil getting deep and relatively increased root amount in deeper soil layers.

在传统灌溉-优化施肥条件下，冬小麦单位面积总分蘖数比传统水肥减少，成穗率降低，单位面积穗数有所减少，穗粒数、千粒重无显著性差异；株高基本无变化；基部节间长度缩短，充实度略微增高，穗下节间增长；中后期叶面积指数略低于传统水肥；起身至成熟干物质积累量动态变化过程与传统水肥十分接近，但抽穗至成熟形成的干物质量增加；旗叶、倒2叶倒3叶、倒4叶叶长及总叶面积有所减少，叶片相对增厚；冠层平均叶倾角大，消光系数小，冠层各层的透光率较高，株型紧凑；旗叶叶绿素含量动态变化与传统水肥十分接近；0-120cm土层总根量与传统水肥也差异不大，但根长密度和根重密度随土层深度递减速度较慢，根系在下层土壤的分布相对增多。

The capacity of single pile will enhance when the length and diameter of pile increases, but effect of pile diameter is more obvious. While pile diameter increases 20、40 and 60 percents, the capacity of pile will enhance 20.4、53.7 and 78.1 percents. And with the effect of mud-cake, the capacity of single bored pile will fall down nearly 20 percents, and pile-side resistance will also reduce 15 — 35 percents. In the centrifuge tests, when the relative displacement between pile and soil was 45 —85mm, which is much more than the criterions, the pile-side resistance will become most. Meanwhile the intenerated value of utmost resistance is close to the resistance in situ. In the pile group tests, the capacity of pile group , which the space among piles increases from 2D to 3D、 4D and 5D , will enhance 6.1、9.6、18 percents .

当桩径增加20%、40%、60%时，桩承载力分别增长了20.4%、53.7%和78.1%；在考虑泥皮效应后单桩侧摩阻力减小15～35%，极限承载力减小18%～24%，且减小率随桩径的增加而变小；试验中桩身侧阻软化值与原型桩实测侧阻软化值接近，且极限侧阻所对应的桩土相对位移试验要比规范值大得多，约为45～85mm；同时群桩极限承载力随桩距的增大而增加，其中桩距为3D、4D、5D的群桩承载力分别比间距为2D的群桩高6.1%、9.6%和18%；其承载力效应系数η接近或大于1，并随着桩间距的增大而不断提高；群桩侧摩阻力沿深度的分布与单桩略有不同，即桩身上部由于承台的作用，侧阻削弱，但桩身中部侧阻具有增加的趋势。
