低级公路上的曲线一般采用简捷的放样方法,也可以满足质量上的要求。如采用偏角法,使用经纬仪来施测,效率不高,同时有些低级技术人员(领工员)对仪器的使用不够熟练,如采用这种简捷的放样方法,则是比较方便的。一、应用的范围在交角I=40°和半径为500公尺以内时,采用这种简捷放样法为宜。“六级”路一般是在此范围以内。如果角度大于40°、而半径小于500公尺,或半径大而角度小时,也可以采用。
The curve on the low-grade highway generally adopts the simple method of setting out the loft, also can satisfy the quality request. Such as the use of declination method, the use of theodolite to test, the efficiency is not high, while some low-level technical staff (staff) on the use of the instrument is not proficient, such as the use of such a simple lofting method is more convenient. First, the scope of application In the intersection I = 40 ° and radius of 500 meters or less, the use of this simple method is appropriate. “Six” road is generally within this range. It can also be used if the angle is greater than 40 ° and the radius is less than 500 meters or the radius is large and the angle is small.
