Weathered sandstone-containing subway station foundation pit excavation equipment selection method
The invention discloses a weathered sandstone-containing subway station foundation pit excavation equipment selection method. The method comprises the following steps that (1) geological conditions are surveyed and determined before excavation of a subway station foundation pit, and geological stratums contained in the geology are determined; (2) according to the matching relationship between the rock-soil strength and thickness of each geological stratum and excavation equipment, the work efficiency assignment of each geological stratum and the excavation equipment is determined; and (3) the excavation equipment of each geological stratum is selected according to the working efficiency assignment. According to the method, for the weathered sandstone-containing subway station foundation pit, a geological condition and optional equipment configuration table is established before excavation of the foundation pit, various excavation schemes are analyzed, and the scheme with the optimal engineering value is obtained through combination, comparison and selection. The method reduces selection errors caused by human limitation, avoids resource waste, and supports safe and efficient engineering construction.
本发明公开了一种含风化砂岩地铁车站基坑开挖设备选定方法，包括以下步骤：(1)在地铁车站基坑开挖前勘查确定地质情况，确定地质包含的地质层；(2)依据各地质层的岩土强度、厚度与开挖设备的匹配关系，确定各地质层与开挖设备的工效赋分；(3)依据上述工效赋分高低选择各地质层的开挖设备。本发明针对含风化砂岩地铁车站基坑，在基坑开挖前建立地质情况及可选设备配置表，分析各类开挖方案，进行组合及比选，得出工程价值最优方案。该方法减少了人为局限性的选择失误、避免资源浪费、支撑工程安全、高效施工。
