摘要
结合江西省水土保持科学研究所已完成的公路水土保持监测工作,总结了体积法和桩钉法等土壤侵蚀常规监测方法和技术在实践中的运用,计算了赣定高速公路建设期土壤侵蚀模数和平均每千米土壤侵蚀模数分别为14 524 t/(km2.a)和114 t/(km2.a);公路项目建设期重点监测区域土壤侵蚀模数技术指标分别为取土场边坡22 540t/km2.a,台面10 500 t/(km2.a);弃土场边坡25 990 t/(km2.a),台面14 010 t/(km2.a);路堤、路堑和施工场地边坡分别为16 270 t/(km2.a)1、4 450 t/(km2.a)6、590 t/(km2.a).
On the basis of the monitoring practice along the new-built highway by Institute of Soil and Water Conservation in Jiangxi Province, this paper applied the volume method and the peg method to the routine monitoring practice of the soil erosion, and calculated the soil erosion modulus during construction period and the soil erosion modulus per kilometer along Ganding Highway, which were 14 524 t/（ km^2·a） and 1 14 t/（ km^2· a） respectively. During the construction period, the main technique indices of the soil erosion modulus in the important monitoring areas were as follows： The soil erosion modulus of the slope was 22 540 t/（km^2· a） ;that of the table-board was 10 500 t/（km^2·a） ,that of the slope of the abandoned soil field was 25 990 t/（km^2·a）, and that of the table-board was 14 010 t/（km^2·a）. The soil erosion modulus of the road embankment slope, the cutting slope, and the construction yard was 16 270 t/（ km^2·a）, 14 450 t/（ km^2·a）. and 6 590 t/（km^2·a） respectively.
