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. REFERENCES Choo, C.O., Takahashi, M. &
