ABSTRACT

In western China, with plenty of transportation infrastructures being constructed, many man-made slopes have been formed in the highway constructions along the highway routes. Fortunately, most of these man-made slopes were in middle or small scales. However, in the procedure of slope design as well as potential landslides controlling, there are many problems and error viewpoints, such as slope angle is determined mainly on the basis of designers’ experience without considering the lifetime of control projects, calculating slope satiability and optionally choosing remedial measurements. If not well resolved, these problems will affect not only the safety of highway operation, but also project investment. Based on the experiences in the highway engineering, these problems have been summarized in detailed and discussed in this paper. Some advices have also been put forward, which could be beneficial to the highway construction and operation.

Keywords: Highway engineering; landslides; safe handling; slope project

ABSTRAK

Di kawasan barat China terdapat banyak infrastruktur pengangkutan yang dibina, banyak cerun buatan manusia yang telah terbentuk dalam pembinaan lebuh raya sepanjang laluan lebuh raya. Mujur, kebanyakan cerun buatan muatan adalah dalam skala tengah atau kecil. Walau bagaimanapun, dalam prosedur mereka bentuk cerun serta kawalan tanah runtuh yang berpotensi berlaku, terdapat banyak masalah dan sudut pandangan ralat, seperti sudut cerun yang ditentukan hanya berdasarkan pengalaman pereka tanpa mempertimbangkan jangka hayat projek kawalan, pengiraan kebolehnampakan cerun dan memilih ukuran pemilihan secara pilihan. Sekiranya tidak dapat diselesaikan dengan baik, masalah ini akan memberikan kesan bukan sahaja kepada keselamatan operasi lebuh raya, tetapi juga kepada pelaburan projek. Berdasarkan pengalaman dalam kejuruteraan lebuh raya, masalah ini diringkaskan secara terperinci dan dibincangkan dalam kajian ini. Beberapa nasihat juga telah dikemukakan yang boleh memberi manfaat kepada pembinaan dan operasi lebuh raya.

Kata kunci: Kejuruteraan lebuh raya; pengendalian yang selamat; projek cerun; tanah runtuh
