摘要
盐渍土评价是盐渍土地区公路工程设计和建设的基本依据,其准确性直接影响着工程设计的科学性和合理性,也是保证工程设计质量的基本条件。通过对比公路工程与工民建、铁路等其它工程的盐渍土评价体系,分析了公路工程与其它工程对盐渍土划分的差异,以及公路工程标准自身对盐渍土划分相悖的情况,指出了当前公路工程对盐渍土评价的不统一性。分析认为,导致盐渍土评价混乱性的根本原因是氯硫比定义有差异,通过理论与实践两方面的分析,认为公路工程应沿用工民建中的氯硫比定义,同时保留自身对盐渍土的细化和扩展,以避免评价结果的不统一,为工程设计提供科学合理的盐渍土评判结果。
The accurate evaluation of saline soil was the fundamental basis for the design and con-struction in Highway engineering,which directly influenced the construction quality and the project cost. Through a comparison of Highway engineering to Railway Engineering,Industrial and civil buildings,this paper analyzed the evaluated differences of saline soil between Highway engineering and other engineer-ing,also the evaluated contradictions by Highway engineering itself was mentioned.Analysis showed that these difference and contradictions was originated in the chlorine-sulfur ratio,which divided the saline soil into different category and was given different disease to engineering construction.By the analysis both theory and practice,the authors considered that the Highway engineering should continue to use the definition of chlorine-sulfur ratio in Industrial and civil buildings,and persist the refinement and expan-sion for the evaluation of saline soil.This reasonable suggestion not only could help avoid the evaluated differences and contradictions of saline soil,but also provide scientific and rational assessed results for engineering design in saline soil area.
