特殊岩土工程的施工 - 连续墙

前言

CEN/TC288（技术委员会）制定本欧洲标准《特殊岩土工程的施工》，其秘书处由法国标准化协会（AFNOR）承担。

欧洲标准将通过出版同样内容的刊物或是通过审议，最迟于2000年7月转换为国家级标准。而所有与之相违背的国家级标准最迟必须在2000年7月之前取消。

根据CEN/CENELEC内部章程规定，以下国家的标准化机构将负责推广应用此欧洲标准：德国、奥地利、比利时、塞浦路斯、丹麦、西班牙、爱沙尼亚、芬兰、法国、希腊、匈牙利、爱尔兰、冰岛、意大利、拉脱维亚、立陶宛、卢森堡、马耳他、挪威、荷兰、波兰、葡萄牙、捷克共和国、罗马尼亚、独联体、斯洛文尼亚，瑞典和瑞士。

TC 288的目的是使岩土工程施工的技术标准化，包括试验监控方法，以及材料要求的标准化。它已委托WG1，用于支撑的连续墙或密封连续墙。本标准不包括挡栏的施工，见EN1536。特殊岩土工程的施工-钻孔灌注桩。

此文件同欧洲标准7-第1部分：土工设计，一般规则(ENV1997)相匹配。后者涵盖了条款8中支撑构造物的设计，并提供了关于工程监控方面的指示。本标准只在非常必要的情况下才会涉及设计问题，例如钢筋笼的定义；相反，此标准完全涵盖了施工和施工监控方面的问题。

由10个国家的代表组成的工程组制定了此标准，包括7个国内或国际文件，并系统地制订了技术标准。

Foreword

This document (EN 10216-3:2002) has been prepared by Technical Committee EC/TC 29, "Steel tubes and fittings for steel tubes", the secretariat of which is held by UNI.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by November 2002.

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.

ISO 657-1 : 1988 (E)

Table 1 — Dimensions and sectional properties of hot-rolled equal-leg angles (concluded)

NOTES

1. Member countries may choose, to be included in their national standards, the sizes which are required to meet their demand.
2. For the angles so chosen, only thicknesses which can be rolled in their mills to meet the demand of the users may be selected from the list of thicknesses corresponding to equal angles in table 1.
3. The sectional area has been calculated using the formula

   S = [l/2 A - l) + 0,214 6 (r_root² - 2r_toe²)] × 1/100

   where
   

   S is the sectional area, in square centimetres;
   

   l is the thickness, in millimetres;
   

   r_root is the root radius, in millimetres;
   

   r_toe is the toe radius, in millimetres;
   

   A is the leg length, in millimetres.

4. Mass is calculated on the basis of density of steel of 7,85 kg/dm³.
