The results show that larger influencing radius can be brought about with the larger load on pile top or larger slenderness ratio of pile; and better soil can have smaller influencing radius.
用来分析桩侧土影响半径 rm,结果表明,随着桩顶荷载 P 增大,桩长细比 L/d 增大,都会使 rm扩大;土质越好,rm越小。

Under complicated geological conditions,large slenderness ratio ultra-deep well sinks in the ultra-soft soil by prevented sinking method,sinks in hard soil by assisted sinking method,and in the process of sinking to take difficult technical measures of anti-tilt,correcting,and prevent sudden sinking to make large slenderness ratio ultra-deep wells vertically and evenly sink in the position.
复杂地质条件下,大长细比超深沉井在超软土层中下沉采取阻沉技术,在硬土层中下沉采取助沉技术,并在下沉过程中采取防倾斜、纠偏和防突沉较难技术措施,使得大长细比超深沉井垂直、均匀下沉到位,取得了较好的经济效益和社会效益。

英国剑桥大学的科学家把液态镓滴在硅表面上，然后科学家把它转向少量含有甲烷的气体，化学反应迫使气体凝聚成极细的碳化硅线，这样“培植”出的纳米花朵比人的头发丝还要细1000倍。另外，科学家还利用硅“培植”出由细线组成的纳米树，即科学家在“培植”细线的过程中改变温度和压力，成功地使这些细线成为大小仅为1～5微米的各种复杂形状——纳米树。
研究人员认为，新工艺可以获得一系列应用，他们现正在研究两个应用方向：用作防水涂覆层和用作新型太阳能电池的主要成分。
