摘要
冲积扇地层产状有时非常平缓,为了准确预报其中地下工程施工遇到的岩性特征,需掌握地层空间分布形态,因此应对地层产状进行精确测量。但是传统的罗盘测量方法不能满足现场测量产状的要求,为此专门设计采用高精度GPS测量方法,测定地层面状要素上多点的坐标,通过数学计算完成研究区地层产状测量。
As a rule,attitudes of alluvial-fan deposit strata are very gentle.In order to predict exactly lithological characteristics at underground projects in an alluvial-fan,it is necessary to know the spatial distribution configuration of the strata by measuring the attitudes accurately.But as the conventional measuring apparatus in field investigation geologic compass cannot satisfy such requirements for the special purpose.The authors developed a new method to determine the strata attitudes by acquiring the multi-point spatial coordinates of special surface-like geological elements with high-resolution GPS.
