建物敷地の地盤解析装置

Ground analyzing apparatus for building plot

Abstract

(57)【要約】 【課題】地盤調査試験が容易となる建物敷地の地盤解析 装置の提供。 【解決手段】スウェーデン式貫入試験の試験結果であ る、捻り角錐83への荷重Wswと、捻り角錐83を回転操 作して所定深さ貫入させた際の半回転数Nswと、地盤 の圧密層の厚さ寸法Hと、建物の単位面積当たりの荷重 qとに基づいて、試験した点の地盤沈下量Sを算出する 地盤沈下量算出手段22を設け、測定現場においてリアル タイムで、地盤沈下の傾向を把握可能とし、様々な建物 の傾斜傾向を速やかに予測できるようにし、これによ り、試験開始後速やかに、試験すべき地点が明確とな り、必要最低限の地点について試験を行えばこと足りる ようになり、データ採取にかかる手間と時間とが軽減さ れ、地盤調査試験が容易となる。
PROBLEM TO BE SOLVED: To provide a ground analyzing apparatus for a building plot, which facilitates a ground investigating test. SOLUTION: The ground analyzing apparatus is comprised of a ground subsidence calculating means 22 for calculating a ground settlement S at a tested location, based on a load Wsw on a wrenched pyramid 83, the number Nsw of half-rotations obtained by rotating the wrenched pyramid 83 to penetrate the same to a predetermined depth, a thickness H of a consolidation layer of the ground, and a load q per unit area of a building, which parameters are test results of the Swedish sounding method. Thus, the tendency of the ground settlement can be grasped in the measurement field in real time, whereby inclination tendencies of various buildings can be quickly predicted. As a result, immediately after starting of the test, locations which should be tested are made clear, and therefore test is conducted only at necessary minimum locations, which saves labor and shortens a period of time required for data sampling, to thereby facilitate the ground investigating test.
