double ring

Compared with the internal bracing systems of retaining for the deep foundation pit in the basement of certain mansion in Fuzhou,the advantages of retaining the construction of the foundation pit with the system of a double ring,a double layer and boring grout piles lie in its better stability,less displacement,larger site area and lower project cos t.

对福州某大厦地下室深基坑支护的几种内支撑体系的比较分析，采用双环双层内支撑体系与钻孔灌注桩共同组成的基坑支护结构，具有整体稳定性好、桩顶位移小、开挖工作面大、工程造价低的优点，解决了软土地基中地下室平面复杂、施工现场小，相邻建筑近的基坑支护问题。

In this paper,we first introduce the conception of quasi-cyclic codes,then thoroughly study the method of constructing quasi-cyclic codes,and finally discuss the connection between quasi-cyclic codes and double cyclic codes and the implementing method of double cyclic codes encoding circuit.

文章首先简述了准循环码的概念,然后较为深入地研究了准循环码生成方法,最后讨论了双环循环码与准循环码的关系及其编码的电路实现。
