现浇泡沫轻质土典型工程应用概述

The Summary of Several Typical Engineering Applications of Cast-in-situ Foamed Lightweight Soil

泡沫轻质土是一种具有轻质、自立、耐久、高流动性等优点的新型工程材料,能解决传统混凝土和土解决不了的岩土工程地质治理问题,同时能节省造价、缩短工期,节能环保,目前广泛应用于道路扩建、桥台台背换填、铁路路基、高填路堤等领域,本文就某几处典型工程应用状况进行论述。

Foamed lightweight soil is a n ew engineering material with lightweight, self - standing, durability, high mobility and oth-er advantages, can solve the geological problem of geotechnical engineering which can not be solved by conventional concrete and soil, as well as saving the cost, reducing the time limit and saving energy. At present, it is widely used in the field of road expansion ,abutment back filling, railway subgrade and high embank-ment. In this paper, several typical engineering applications are discussed.
