The first is to generate the shrinkage settlement under curing. The second is that engineering properties change under construction by material separation of soil cement and contamination of the groundwater. The third is that many cold joints occur. Therefore, the shrinkage behavior of soil cement during water curing period was examined, and next, expression process of hydraulic conductivity and compression strength of soil cement were clarified, and the effect of gravel rate and water cement ratio on them was examined. In addition, permeability test and shear strength test were carried out on the cold joint model test-pieces. Then, hydraulic conductivity and shear strength of the cold joint in soil cement were clarified. Finally, the some countermeasures for the construction of continuous underground wall were proposed.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3604"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
