| 1. | On reason for longitudinal crack failure of the entry and its solutions 采煤平巷纵向裂缝破坏原因与处治 |
| 2. | Crowfoot longitudinal crack 爪形纵裂缝 |
| 3. | Its stability is destroyed with longitudinal cracks of embankment caused by asymmetric settlement of permafrost 由于阴阳坡差异引起路基不均匀沉降而导致的路面纵向裂缝病害严重影响了路基的稳定性。 |
| 4. | The longitudinal cracks have become the main subgrade distress type in the permafrost regions , and there is not a effective solution now 纵向裂缝目前已成为多年冻土地区路基病害的主要类型之一,目前还没有一种有效的解决方法。 |
| 5. | Synthesized the domestic and international current result , the paper presents the geogrids and flexible beams treating technology to ravel out the distress of the longitudinal cracks 综合国内外现有成果,本文提出了土工格栅及柔性枕梁等处治措施,从深层次解决青藏公路纵向裂缝的危害问题。 |
| 6. | Longitudinal crack formed when screw steel rebar is cold - bended was analyzed . the result indicates that ununiformly distributed silicate inclusions contributed to the longitudinal crack . protective measurements were also provided 摘要对螺纹钢筋由冷弯产生的纵向裂纹进行了分析,结果表明,硅酸盐夹杂物分布不均匀是造成螺纹钢筋冷弯纵向裂纹的主要原因,并提出了相应的预防措施。 |
| 7. | In the dam foundation restraint area , mgo can be mixed into concrete to prevent dam longitudinal crack . research on autogenous volume change of rcc mixed with mgo , and research on thermal stress compensation of darn foundation prove that rcc mixed with mgo plays a role in dam crack control 在材料措施方面,深入研究高碾压混凝土坝基础约束区采用外掺mgo措施,利用其微膨胀性能补偿坝体降温过程中产生的温度应力,以防止大坝纵向裂缝的发生。 |
| 8. | Results showed that the temperature distribution of the traditional embankment was asymmetrical ; the asymmetrical status was changed after ripped - rock revetment was installed and the soil under the ripped - rock was cooled obviously ; the ripped - rock revetment could cool embankment and adjust the temperature difference between the north - facing slope and the south - facing slope ; the ripped - rock revetment was an available technique to protect embankment from thawing settlement and longitudinal cracks in permafrost regions 结果表明:普通路基的阴阳坡两侧温度分布极不对称;铺设抛石护坡后,这种状况得到了很大改善,并且抛石护坡下土体温度明显降低;抛石护坡能够降低路基温度和调节路基阴阳坡的温度差异;抛石护坡是多年冻土区防治路基融沉和纵向裂缝病害的一种可行措施。 |
