1.苏联近年来沥青混凝土路面的大量破坏,不可能全都归罪于现行的柔性路面设计理论的不完善。 2.路面大量破坏的主要原因总结有如下列: a.设计者机械地应用设计理论,没有充分地考虑当地的自然条件及筑路材料的性质,特别是那些颗粒组成极不一律的砾料方面; 6.设计者常企图尽可能降低修筑路面的费用,而昧然采用一些计算参数的最大值,如土与地方筑路材料(像性质不一致的砾料)的形变模量; B.某些计算参数值过高,例如在苏联道路科学研究院拟定的“柔性路面设计须知”中,关于砾料的形变模量,即未曾考虑砾料中小于0.5公厘的细土粒的含量; r.对许用于修建沥青混凝土路面基层的那些材料的形变模量,未曾提出明确的要求;关于路面结构问题,在上述的“须知”中,亦完全未加反映,而这一方面在应用当地的、大部分性质都不一致的筑路材料中,却有极重要的意义; 3.调查许多有高级路面的破坏路段,证实许多筑路单位所使用的地方材料的品质,并未符合要求。他们使用了污染的砾料,其中小于2公厘的颗粒含量大于25%,小于0.074公厘的大于10%,而这些都超过了允许的限度。此外,应用地方材料修建路面基层,在材料的一致性和密实度方面,亦均不符合要求; 4...

1.苏联近年来沥青混凝土路面的大量破坏,不可能全都归罪于现行的柔性路面设计理论的不完善。 2.路面大量破坏的主要原因总结有如下列: a.设计者机械地应用设计理论,没有充分地考虑当地的自然条件及筑路材料的性质,特别是那些颗粒组成极不一律的砾料方面; 6.设计者常企图尽可能降低修筑路面的费用,而昧然采用一些计算参数的最大值,如土与地方筑路材料(像性质不一致的砾料)的形变模量; B.某些计算参数值过高,例如在苏联道路科学研究院拟定的“柔性路面设计须知”中,关于砾料的形变模量,即未曾考虑砾料中小于0.5公厘的细土粒的含量; r.对许用于修建沥青混凝土路面基层的那些材料的形变模量,未曾提出明确的要求;关于路面结构问题,在上述的“须知”中,亦完全未加反映,而这一方面在应用当地的、大部分性质都不一致的筑路材料中,却有极重要的意义; 3.调查许多有高级路面的破坏路段,证实许多筑路单位所使用的地方材料的品质,并未符合要求。他们使用了污染的砾料,其中小于2公厘的颗粒含量大于25%,小于0.074公厘的大于10%,而这些都超过了允许的限度。此外,应用地方材料修建路面基层,在材料的一致性和密实度方面,亦均不符合要求; 4.国立全苏道路科学研究院在1956年修正的“须知”中,已将上述几项缺点加以消除。在此新“须知”中,并附载有设计与施工单位直接测定土与筑路材料形变模量的方法指示,这样,也就可能充实足够的、能说明土与筑路材料在各种不同自然情况中的强度的实际资料; 5.在新“须知”中并指出了应以什么方向来修正柔性路面设计理论,尤其是在确定行车震动对于路面、特别是土的强度的影响方面。此外,对于在天然含水量超过90%(对塑性下限而言)的过湿土壤上设计路面,亦需要作出一更新的完善的计算理论。按照行车的重现率(特别是重型车辆)的安全系数值,以及参照路面厚度的临界挠度等等亦均极需加以确定。在这一方面,理论的研究必须分别结合各种不同自然条件中所发生现象本身的物理实质而进行。

In this peper, the author demonstrates the factors which affect the water-resistance of compacted soils, especially the degree of wetting by euviroments and the degree of compaction. It revealed the possibility, through laboratory test that at arid vegiuns (little possibility of wettiug or good hydrological conditions) the soil in embanbment could be compactell at the mois ture content below the optimum, and the wet-strength of compacted soil is higher than that at optimum. The author had also made the wetting and drying test of compacted. soil and found that the higher the degree of compaction, the larger the water-resistance of the compacted soil. The results of this research would be usefal to solve the compaction problems at arid regions.

压实士在润湿作用后的表现如何,要看润湿作用的强烈程度和路基土的压实程度而定。在西北缺水地区,由于湿源不足,路基土可以在低于最佳含水量时压实。此时,压实土在润湿后的强度反较在最佳含小量值时压实的小。借助于增加压实工作量而获得的高密实度的土,在反复干湿的作用下,是能保持较高的水稳定性的。因此,在缺水地区我们可以在较低的天然湿度下进行压实;同时也可以用较重的来压实工具压实,此时可获得高强度的土。

論文总結了近几年来苏联学者在研究冲填密实方面的工作,并进一步通过大量的試驗资料的分析整理,具体的考查了用均匀細砂进行水上冲填时,影响冲填密实度的因素,并用图表及公式建立了冲填密实度与其影响因素間的关系。实驗研究与分析工作証明了在冲填过程中对泥浆濃度及其单寬流量加以适当控制时,可以得到較高的冲填密实度,而无需进行使冲填造价变貴及冲填期限拖长的各种旨在加强均匀細砂冲填密实度的人工措施,这对提高冲填建筑物的質量及使冲填施工经济合理有重大意义。在研究过程中考查了現场条件下进行試驗的方法,探討了整理資料的方法,并将所得成果和苏联諸学者所得的成果作了比較,这对今后有关此間題的研究工作会有帮助。
