公路工程路基石方和岩石地层造孔定额存在的问题及建议

Existing Problems and Suggestions on the Pore-forming Quota of Subgrade Stonework and Rock Stratum of Highway Engineering

通过对现行公路定额路基工程六级土石分类与十六级土石分类的对照,量化了公路路基工程定额中各类岩石的抗压强度指标;通过公路定额各类岩石的强度指标与国标和行业规范的岩石强度分级对比,总结出公路定额与行业规范岩石强度指标划分的较大差异;通过分析工作实践发现的问题,提出了工程设计和造价编制中的注意事项;通过相关行业定额岩石强度指标划分的对比,对公路工程定额的修编完善提出建议。

The compressive strength indicators of various rocks in the highway subgrade engineering quota are quantified by comparing the current highway subgrade engineering quota with the grade 6 soil and rock classification and the grade 16 soil and rock classification;the significant differences in the classification of rock strength indicators between the highway quota and industrial specification are summarized by comparing the strength indicators of various types of rocks in the highway quota with the rock strength grading in national standard and industrial specification;the matters needing attention in the engineering design and cost compilation are put forward by analyzing the problems found in work practice;the suggestions are put forward for the revision and improvement of the highway engineering quota by comparing the classification of rock strength indicators in relevant industrial quota.
