中文摘要：
高填方暗道在西部沟壑地区得到越来越广泛的应用，但有关高填方暗道周边土压力分布的计算尚不十分清楚，需要进一步研究。通过对山西平朔东露天煤矿输煤暗道周边土压力现场测试资料分析，得出了高填方输煤暗道周边土压力分布和变化规律，对暗道周边的应力状态有了更为清晰地了解。试验结果表明，高填方暗道结构顶部存在竖向土压力集中现象，高填方暗道侧部竖向土压力分布呈现如下规律：当填土高度较低时，土压力随填土高度增加较快；当填土高度较大时变化缓慢。高填方暗道竖向土压力计算时，当填土高度较低时，宜采用土柱法；填土高度较大时宜选用顾安全公式法。与暗道结构相比，公路桥涵与地下埋管尺寸和刚度较大，建议计算侧向土压力系数采用静止土压力系数。
英文摘要：
The conduits under high earth-fill have become more widely used in gully area in Western China; but the calculation of thecircumjacent earth pressure on it is still not very clear. That needs further study. Based on the field tests on circumjacent earthpressure of the coal handling conduit in Shuozhou of Shanxi Province, the distribution and variation laws of the circumjacent earthpressures, stress state around the conduit are obtained. The test results show that there is a stress concentration for vertical earthpressure at the top of the coal conduit. The earth pressure increases faster when the filling height is lower; but the ratio of increasegets slower for the vertical earth pressure on the side of the conduit. The soil core method is preferably used when the filling height islower; but the formula named ＇Gu Anquan＇ is preferably applied to calculating the vertical earth pressure. Comparing culverts andunderground penstock, the dimensions and rigidities of the high fill channels are larger, and using the coefficient of earth pressure atrest is recommended when calculating the coefficient of lateral earth pressure.
