适用于公共工程合同的《通用技术条款手册-工程》第69分册：地下工程

II. 注释说明的附录

2.1. 参与者资质

企业咨询文件编写指南（参见第69分册注释说明附录2）第一段中就有关参与者所需的资质进行了强调，并就此提出相关建议。这是非常重要的一点，我在此特提醒各位注意。

特别是，监理的现场代表，经常被称作工程经理，应提供足够的技术能力证明，否则应当要求进行必要的技术考核。

监理应该清楚，一项地下工程的施工管理和最终结算，与露天工程相比，需要更加细致和周全考虑。对此增加了多项新的条款，诸如要求承包商提交日报告及月报告（参见标准特殊技术条款手册第16条规定）或相关的测量和检测报告。

2.2. 结算方式

监理应特别注意有关项目的效益，应系统地执行《通用技术条款手册》及其附件所确定的结算方式和编写的价格明细表。

事实上，这些文本明确规定了构造物各部分的结算方式：工地建点，支撑工程，挖掘工程以及测量工作等。

2.3. 标准断面

线性地下工程使用标准断面。

为了不增加断面数量，对于每个标准断面，宜规定按单价支付的支撑工程数量的剪刀差值。这些数量应该根据地层的性质进行调整，但标准断面的性质不得变化。

作为示意性说明，给出标准断面长度的总和可能是有用的。但是不宜把标准断面作局部使用，除非已掌握了足够的地层资料。

ULTE 82-25 bis. -2.

2.4. 卫生和安全问题

1976年12月6日颁发的第76-1106号法令，明确规定了安全问题的整体概念。

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of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by November 2002.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.
