花土沟民用机场盐渍土地基处理试验分析

Huatugou Civilian Airport Salty Soil Treatment Test Analysis

花土沟机场为盐渍土场地,通过对花土沟机场场地内实验区采用的土工布包裹混山石隔离法和土工布包裹砂砾石隔离法处理盐渍土地基的效果比较,级配砂砾石的压实效果优于混山石,混山石的隔盐效果比级配砂砾石的好,综合考虑级配砂砾石与混山石的压实效果及隔盐效果等因素,实验结果建议地基处理时,以1.5m厚隔盐层结构底部采用0.3m厚混山石,上部1.2m厚采用级配砂进行处理.

Through Huatugou airport site in the experimental area of the geotextile part and parcel ofmixed rocks isolation method and geotextile package sand gravel isolation method treatment of saline soilfoundation effect, graded sand gravel compaction effect is better than that of mixed rocks, mixed rocksacross the salt effect than of graded sand gravel, comprehensive consideration of graded sand gravel andmixed rocks of compaction effect and isolation effect of salt and other factors, subgrade treatm ent, 1. 5 mthick insulation layer at the bottom of the structure using 0. 3 m thick mixed rocks, upper 1. 2 m thick withgraded sand processing
