Degradation or decline of soil quality that cause shallow slope failure may occur due to physical or chemical processes. It can be triggered off by natural phenomena, or induced by human activity through misuse of land resources, excessive development and urbanization leading to deforestation and erosion of covered soil masses causing serious threat to slopes. The extent of damage of the slopes can be minimized if a long-term early warning system is predicted in the landslide prone areas. The aim of the study was to characterize chemical properties of stable and unstable slope along selected highways of Malaysia which can be manipulated as indicator to forecast shallow slope failure. The elements in soil chemical properties contributed to each other as binding agents that affected the existing soil structure. It could make the soil structure strong or weak. Indicators that can be used to predict shallow slope failure were low content in iron, lead, aluminum, chromium, zinc, low content of organic carbon and CEC.
由于物理或化学过程，可能会发生导致浅层边坡失稳的土壤质量退化或下降。它可能由自然现象引发，也可能因人类活动对土地资源的滥用、过度开发和城市化导致森林砍伐以及覆盖土壤的侵蚀而诱发，从而对边坡造成严重威胁。如果在滑坡易发地区建立长期预警系统，边坡的破坏程度可以降至最低。本研究的目的是表征马来西亚选定高速公路沿线稳定和不稳定边坡的化学性质，这些性质可作为预测浅层边坡失稳的指标。土壤化学性质中的元素相互作用，作为影响现有土壤结构的粘合剂。它可以使土壤结构变强或变弱。可用于预测浅层边坡失稳的指标是铁、铅、铝、铬、锌含量低、有机碳含量低和阳离子交换量低。
