Abstract

A case study was carried out in Taiping to visualise, assess and review pertinent technical issues and the reality as well as the role of geologists in the activity and processes of hill site developments. Developments on hill site are commonly associated with slope failures and landslide geohazards. This study was instigated by a complaint made by a house owner who has been so worried about the safety of her house because of its very close proximity to a dangerous slope. An engineering geological assessment has been conducted on the slope by means of brief field study. The occurrences of geohazards and risks of geodisaster have been qualitatively assessed via filed observation, expert judgement and past photographic records of geodisaster incidents. The studied slope is a slope cut in highly weathered granite rock mass with well-developed relict structures. Kinematic stability analysis of the relict discontinuity data suggested that the slope is unstable and potentially to fail in wedge, planar and/or toppling failure. The results of the analysis are supported by the occurrences of failure scars and rock boulders accumulated at the foot of the slope. Although the slope has been installed with steel wire mesh, however its method of installation and the design was not in accordance with the expected engineering specification. Worse still, at the top of the slope another luxurious housing project is in the progress of changing the physical and geomorphological features of the hill slope. Even though various rules, guidelines and acts have been in place to control developments on hill site, in reality the situation is really sad and regrettable. A lot of questions can be raised up on how this situation could happened. What should the role of professionals and the stakeholders in this kind of situation be? Above all, geologists should be more proactive to heighten their professionalism and to advocate public awareness about geohazards and risks of geodisaster. Geologists should also be given more authority to control any development activities on hill sites and risky areas.
