SELECTION METHOD OF GROUND IMPROVEMENT METHOD, AND GROUND IMPROVEMENT METHOD
PROBLEM TO BE SOLVED: To provide a selection method of a ground improvement method capable of preventing a delay of a construction period and of reducing costs in ground improvement.SOLUTION: The selection method of the ground improvement method comprises an investigation step S30 to investigate a ground using a standard penetration testing method, a mixture step S60 to obtain a mixture sample by mixing a soil sample that is collected by a sampler for a standard penetration test, which penetrates the ground in the standard penetration testing method, and a predetermined amount of solidification material, a filling step S70 to fill the inside of a cylindrical body with the mixture sample, an extraction step S80 to extract a solidified soil sample from the cylindrical body as a specimen for a compression test after a predetermined solidification time passes from the time of filling of the mixture sample, a measurement step S90 to measure compressive strength of the specimen by applying pressure to the specimen from one side, and a determination step S100 to determine whether a columnar improvement method is adopted or not based on a result of the measurement step S90.SELECTED DRAWING: Figure 1
【課題】地盤改良における工期の遅延化を防ぐと共に、費用を削減することが可能な地盤改良工法の選定方法を提供する。【解決手段】地盤改良工法の選定方法は、標準貫入試験方法により地盤を調査する調査工程Ｓ３０と、標準貫入試験方法において地盤に貫入された標準貫入試験用サンプラーにより採取された土壌試料と予め設定された量の固化材とを混合することにより、混合試料を得る混合工程Ｓ６０と、混合試料を筒体内に充填する充填工程Ｓ７０と、混合試料の充填時から予め設定された固化時間の経過後、固化した土壌試料を筒体内から圧縮試験用の供試体として取り出す取出工程Ｓ８０と、供試体に対して一方から圧力を加えることにより、供試体の圧縮強さを測定する測定工程Ｓ９０と、測定工程Ｓ９０の結果に基づいて、柱状改良工法の採用の可否を判断する判断工程Ｓ１００と、を備える。【選択図】図１
