中国大陆科学探井岩性的VSP地震特征分析

Reinforces the measure not carries on reinforcement processing in view of the right flank main hole in the accumulative stratum and the strong regolith contact surface spot, existence certain flaw.

加固措施没有针对右侧主洞在堆积层与强风化层的界面部位进行加固处理，存在一定缺陷。

Overall average Vp velocity of main hole of 2000m rook is 6. 2km/ s which is correspondent to conclusion with high velocity zone ( 6. 2-6. 3km/ s) of the upper crust in Dabie-Sulu orogenic belt inferred from geophysical methods.

主孔2000m总平均Vp速度为6.2km/s，它与地球物理探测方法获得的大别-苏鲁造山带上地壳具有6.2-6.3km/s高速层结论是一致的。
