拉迪什
拉迪斯
Examples
- Nanoparticles show significant quantum - size effect ( such as energy band discreteness , band gap broadening , blue shift in spectra etc . ) as sizes of particles are smaller than bohr radis of exciton of bulk material with same composition ( for example , cds ’ s bohr radium is 6nm )
当纳米粒子的尺寸小于其块状材料的激子波尔半径时(如cds的激子波尔半径为6nm ) ,能够表现出明显的量子尺寸效应(如能带离散,禁带变宽,光谱蓝移等) 。 - With the retrospection of the developing course of the bored pile foundation and combining with my practical experience , the paper expatiates upon the design principle of percent of fit of the stone - fill grouted concrete and the main factors of the influence strength target , and the final pile technique introduction of the hollow pile of the stone - fill grouted concrete and the precast prestressed concrete ; baesd on the theory of slurry hydraulics , empirical calculation formulas of the radis and height of diffuse slurry are deduced in this paper ; it analyzes the test pile materials of the hollow pile foundation , such as luoyang yi river bridge and dangwang jian river bridge ; the new technique of the hollow pile , which provides the generalization and application with base materials , expounds its feasibilities , adaptabilities and economy
本文通过综合分析国内外钻孔桩基础的发展历程及研究现状，重点讨论了填石压浆混凝土空心桩、预制预应力混凝土空心桩的成桩工艺、填石压浆混凝土的配合比设计原理及影响强度指标的主要因素；根据泥浆水力学原理，导得了考虑各种因素的水泥浆液在预填骨料中的流动影响半径和上升高度；结合河南省洛阳伊河大桥、党湾涧河大桥工程实践，讨论了填石压浆混凝土空心桩基础的质量检测方法及标准；并在此基础上，深入分析了桩侧、桩端承载能力，提出了填石压浆混凝土空心桩的设计计算理论和方法。最后，论证了空心桩新工艺的可行性、适应性、经济性，为大力推广应用空心桩新技术提供了可靠的技术资料。
