治理工程措施选择应充分考虑治理工程功能性的具体要求、在不同工况条件下的安全性及耐久性、工期要求和投资的经济性以及后期维护的要求、工程岩土体性质及其蓄水后的变化、场地条件、施工技术条件、地方材料资源等具体制约因素以及环境保护的要求。

It is found that fabric treated with 20g/L X-cape DRC,60g/L LK-30 has durable oil and water repellence,polyethylene type softener...

试验结果表明，X-cape DRC用量20 g/L、LK-30用量6 g/L、布面pH值6~8时，可获得较好的拒水拒油整理效果，且耐久性良好；调节手感时可加入聚乙烯类柔软剂129、平滑剂HLC。

The experiment shows the specimen's freezing and thawing repellence of 100% recycled aggregate concrete with city garbage melting slag, compared with specimen of the normal concrete whose coarse and fine aggregate's replacement ratio is 0%,the durability number indexes of using water and cement ratio 0.45 and 0.65 respectively decreased 5.3% and 7.9%,but all can satisfy the lowest index for evaluating freezing and thawing repellence.

试验结果表明，城市垃圾熔渣再生混凝土试件的冻融循环抵抗性与粗、细骨料置换率为0%的普通混凝土试件相比，水灰比0.45、0.65时的耐久性指数分别降低5.3%和7.9%，但都能满足评价冻融循环抵抗性的最低指标。

The examination of the steel bar corrosion and the determination of the corrosion condition may provides the foundation data of the reinforced concrete structure residuary load and the structure durability.
