天然地基上扩大基础基坑工程量计算

目前国内公路桥涵施工图设计中,对天然地基上扩大基础基坑工程量计算,基本按单体构造物形状向外沿按1:n的坡率放坡,形成倒置台体形状,粗略计算其体积。本文从施工角度出发,充分考虑施工各环节所发生的各部分工程量,总结出较精确的开挖基坑工程数量计算方法。

Project Calculation of Expanding the Base of Natural Foundation

Currently the construction design of highway bridges and culverts on the basis of the natural foundation excavation to expand calculation forms the basic shape out by single structures along the press 1: n the slope rate of sloping,forming the shapes of inverted units,roughly calculated volume.From the construction point of view,the article gives full consideration to all sectors of construction occurred in various parts of works summed up a more accurate calculation of the number of foundation pit excavati...
