Abstract
Description
2 計測対象位置
Claims (3)
- 計測対象位置における地盤の傾斜角度を測定するための二軸の重力加速度計センサーと、上記計測対象位置における傾斜方位角度を特定する電子コンパスとを内蔵し、設置初期値からの相対的な傾斜角度及び傾斜方位角度のデータを出力可能とする地盤傾斜計において、上記重力加速度計センサーは、角度データ分解能が0.1°以下であるとともに、上記電子コンパスは、方位データ分解能が±1.0°以下であって、上記地盤傾斜計によって計測対象位置における傾斜方位角度を経時的に測定するとともにその標準偏差を算出し、この標準偏差の値が計測対象位置の非傾斜時の標準偏差の値の4分の1未満となった時点が、計測対象位置における地盤の傾斜時であることを確認可能としたことを特徴とする、地盤傾斜計による地盤傾斜確認方法。
- 傾斜方位角度は、0.3秒間隔で測定したことを特徴とする請求項1の地盤傾斜計による地盤傾斜確認方法。
- 地盤傾斜計は、計測対象位置に複数個配置したことを特徴とする請求項1の地盤傾斜計による地盤傾斜確認方法。
