Significant growth have been achieved in many major cities around the world. The demand of better connectivity through various transportation infrastructure has led to ever more reliance to underground space such as tunnels. Hence engineering-wise, a more reliable design reference will provide better ground movement estimation from the ground excavation. The instrument monitoring data for the Klang Valley Mass Rapid Transit (KVMRT-SSP) Line 2, Malaysia in Kuala Lumpur Limestone formation is presented in this paper to assess the magnitude of ground movement during tunnelling works. Back calculation of settlement trough width parameter, K and volume loss, VL are presented in this paper. Based on 13 arrays of ground settlement markers (GSM) records, the averaged back-calculated K is 0.9 whereas VL ranges from 0.16 to 0.21. The information is useful for future tunnelling especially of similar ground characteristics in estimation of ground movement. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021.
