摘要
在盐渍化软土地区修筑道路路基,分析土壤固化剂固化石灰土修筑道路路基的可行性。以典型的盐渍化软土地区———轻纺经济区的道路工程为例,分析轻纺经济区的地质、含盐量;对土壤固化剂固化土(5%石灰+95%原土+固化剂)的击实试验、无侧限抗压强度(7d)、室内回弹模量以及CBR测试,得出土壤固化剂固化土(5%石灰+95%原土+固化剂)均能满足路基相关规范对路床范围内的要求;选取轻纺经济区内道路试验段,从试验路段的弯沉、室外回弹模量、CBR测试及造价上对比分析了石灰土(12%)和土壤固化剂固化土(5%石灰+95%原土+固化剂)修筑道路路基的优劣。
The article analyzes the feasibility of the soil curing agent cured lime soil for road construction when the roadbed is constructed in salinized soft soil region.Taking a road project of textile economic zone in the typical salinized soft soil region as an example,the article analyzes the geology and salt content of the textile economic zone.By the compaction test of soil curing agent cured soil(5% lime + 95% raw soil + curing agent),unconfined compression strength(7 d),indoor resilient modulus and CBR tests,the results show that the soil curing agent cured soil(5% lime + 95% raw soil + curing agent) can satisfy the requirements within the roadbed range of the relative roadbed standard.The article compares and analyzes the advantages and disadvantages of the lime soil(12%) and the curing agent cured lime soil(5% lime + 95% raw soil + curing agent) to construct the roadbed in the tested section of roads in the textile economic zone from the deflection,outdoor resilient modulus and CBR tests,and the construction cost of the tested road section.
